Channel 1 is a step-down (Buck) regulator with an input
voltage range of 6V to 24V providing up to 2500mA output current. 490kHz fixed switching frequency allows
small L/C filtering components. Channel 1 utilizes voltage mode control configured for optimum performance
across the entire output voltage and load range.
Channel 2 is a low-dropout (LDO) regulator providing up
to 600mA output current. The device provides extremely
low output noise, low quiescent current and excellent
transient response.
The controller includes integrated cycle-by-cycle overcurrent protection, soft-start and over-temperature disable features. Independent input and enable pins provide maximum design flexibility.
The AAT2689 is available in the Pb-free 3x4mm 16-pin
TDFN package. The rated operating temperature range is
-40°C to 85°C.

Functional Description
The AAT2689 provides two independently regulated DC
outputs; consisting of a high voltage step-down (Buck)
regulator and a low input voltage linear low dropout
(LDO) regulator. The PMIC is optimized for low cost 12V
adapter inputs, making the device an ideal system-on-achip power solution for consumer communications
equipment.
Channel 1 is a step-down (Buck) regulator with an input
voltage range 6.0 to 24V; providing up to 2500mA output current. 490kHz fixed switching frequency allows
small L/C filtering components.
Channel 1 utilizes voltage mode control configured for
optimum performance across the entire output voltage
and load range. The controller includes integrated overcurrent, soft-start and over-temperature protection. Over-
10
current is sensed through the output inductor DC winding
resistance (DCR). An external resistor network adjusts
the current limit according to the DCR of the desired
inductor and the desired output current limit. Frequency
reduction limits over-current stresses during short-circuit
events. The operating frequency returns to the nominal
setting when over-current conditions are removed.
Channel 2 is a linear low-dropout (LDO) regulator providing up to 600mA output current at a factory set output
voltage. The device provides extremely low output noise,
low quiescent current and excellent transient response.
The controllers include integrated over-current, softstart and over-temperature protection. Independent
input and enable pins provide maximum design flexibility. The AAT2689 is available in the Pb-free 3x4mm
16-pin TDFN package. The rated operating temperature
range is -40°C to 85°C.

AAT2689
PMIC Solution for 12V Adapter Systems
with 2-Output High Performance Step-Down Converters
Applications Information
Output 1 is a high voltage DC/DC Buck (step-down) converter providing an output voltage from 1.5V to 5.5V.
The integrated high-side N-channel MOSFET device provides up to 2.5A output current. Input voltage range is
6.0V to 24.0V. The step-down converter utilizes constant
frequency (PWM-mode) voltage mode control to achieve
high operating efficiency while maintaining extremely
low output noise across the operating range. High
490kHz (nominal) switching frequency allows small
external filtering components, achieving minimum cost
and solution size. External compensation allows the
designer to optimize the transient response while achieving stability across the operating range.
Output 2 is a low voltage, low dropout (LDO) linear
regulator providing 1.8V with up to 600mA output current. The input voltage range is 2.7V to 5.5V. The LDO
provides very low noise output which can be derived
directly from the Output 1 channel.
Output Voltage and Current
Output 1 is set using an external resistor divider as
shown in Table 1. Minimum output voltage is 1.5V and
maximum output voltage is 5.5V. Typical maximum duty
cycle is 85%.

Channel 1 Regulator
Output Capacitor Selection
Two 22μF ceramic output capacitors are required to filter
the inductor current ripple and supply the load transient
current for IOUT = 2.5A. The 1206 package with 10V
minimum voltage rating is recommended for the output
capacitors to maintain a minimum capacitance drop with
DC bias.
Channel 1 Output Inductor Selection
The step-down converter utilizes constant frequency
(PWM-mode) voltage mode control. A 4.7μH inductor
value is selected to maintain the desired output current
ripple and minimize the converter’s response time to
load transients. The peak switch current should not
exceed the inductor saturation current, the MOSFET or
the external Schottky rectifier peak current ratings.
Channel 1 Rectifier Selection
When the high-side switch is on, the input voltage will be
applied to the cathode of the Schottky diode. The rectifier's rated reverse breakdown voltage must be chosen
at least equal to the maximum input voltage of the stepdown regulator.
When the high-side switch is off, the current will flow
from the power ground to the output through the
Schottky diode and the inductor. The power dissipation
of the Schottky diode during the time-off can be determined by the following equation:
PD = IOUT · VD · 1 -
VOUT
VIN
Where VD is the voltage drop across the Schottky diode.
Channel 1 Input Capacitor Selection
For low cost applications, a 100μF/25V electrolytic capacitor is selected to control the voltage overshoot across
the high side MOSFET. A small ceramic capacitor with
voltage rating at least 1.05 times greater than the maximum input voltage is connected as close as possible to
the input pin (Pin 14) for high frequency decoupling.
R3 is rounded to the nearest 1% resistor value.

Channel 1 Thermal Protection
The AAT2689 has an internal thermal protection circuit
which will turn on when the device die temperature
exceeds 135°C. The internal thermal protection circuit
will actively turn off the high side regulator output device
to prevent the possibility of over temperature damage.
The Buck regulator output will remain in a shutdown
state until the internal die temperature falls back below
the 135°C trip point. The combination and interaction
between the short circuit and thermal protection systems allows the Buck regulator to withstand indefinite
short-circuit conditions without sustaining permanent
damage.

Over-Current Protection
The Output 1 controller provides true-load DC output
current sensing which protects the load and limits component stresses. The output current is sensed through
the DC resistance in the output inductor (DCR). The controller reduces the operating frequency when an overcurrent condition is detected; limiting stresses and preventing inductor saturation. This allows the smallest
possible inductor for a given output load. A small resistor
divider may be necessary to adjust the over-current
threshold and compensate for variation in inductor DCR.
The preset current limit threshold is triggered when the
differential voltage from RS1 to OS1 exceeds 100mV
(nominal).

Channel 2 Input Capacitor
Typically, a 1μF or larger capacitor is recommended for
CIN in most applications. A CIN capacitor is not required for
basic LDO regulator operation. However, if the AAT2689
is physically located more than three centimeters from an
input power source, a CIN capacitor will be needed for
stable operation.
CIN should be located as close to the device VIN pin as possible. CIN values greater than 1μF will offer superior input
line transient response and will assist in maximizing the
highest possible power supply ripple rejection. Ceramic,
tantalum, or aluminum electrolytic capacitors may be
selected for CIN. There is no specific capacitor ESR requirement for CIN. However, for 150mA LDO regulator output
operation, ceramic capacitors are recommended for CIN
due to their inherent capability over tantalum capacitors
to withstand input current surges from low impedance
sources, such as batteries in portable devices.
Channel 2 Output Capacitor
For proper load voltage regulation and operational stability, a capacitor is required between pins VOUT and GND.
The COUT capacitor connection to the LDO regulator
ground pin should be connected as close as possible for
maximum device performance. The AAT2689 LDO has
been specifically designed to function with very low ESR
ceramic capacitors. For best performance, ceramic
capacitors are recommended.

DATA SHEET
AAT2689
PMIC Solution for 12V Adapter Systems
with 2-Output High Performance Step-Down Converters
Typical output capacitor values for maximum output current conditions range from 1μF to 10μF. Applications
utilizing the exceptionally low output noise and optimum
power supply ripple rejection characteristics of channel
2 should use 2.2μF or greater for COUT. If desired, COUT
may be increased without limit. In low output current
applications where output load is less than 10mA, the
minimum value for COUT can be as low as 0.47μF.
Channel 2 No-Load Stability
Channel 2 Enable Function
Under normal operating conditions, a parasitic diode
exists between the output and input of the LDO regulator. The input voltage should always remain greater than
the output load voltage, maintaining a reverse bias on
the internal parasitic diode. Conditions where VOUT might
exceed VIN should be avoided since this would forward
bias the internal parasitic diode and allow excessive current flow into the VOUT pin, possibly damaging the LDO
regulator. In applications where there is a possibility of
VOUT exceeding VIN for brief amounts of time during normal operation, the use of a larger value CIN capacitor is
highly recommended. A larger value of CIN with respect
to COUT will effect a slower CIN decay rate during shutdown, thus preventing VOUT from exceeding VIN. In applications where there is a greater danger of VOUT exceeding VIN for extended periods of time, it is recommended
to place a Schottky diode across VIN to VOUT (connecting
the cathode to VIN and anode to VOUT). The Schottky
diode forward voltage should be less than 0.45V.
The AAT2689 features an LDO regulator enable/disable
function. This pin (EN) is active high and is compatible
with CMOS logic. To assure the LDO regulator will switch
on, the EN turn-on control level must be greater than
1.5V. The LDO regulator will go into disable shutdown
mode when the voltage on the EN pin falls below 0.6V.
If the enable function is not needed in a specific application, it may be tied to VIN to keep the LDO regulator in a
continuously on state. When the LDO regulator is in
shutdown mode, an internal 1.5k resistor is connected
between VOUT and GND. This is intended to discharge
COUT when the LDO regulator is disabled. The internal
1.5khas no adverse effect on device turn-on time.
Channel 2 Short-Circuit Protection
The AAT2689 LDO contains an internal short-circuit protection circuit that will trigger when the output load current exceeds the internal threshold limit. Under shortcircuit conditions, the output of the LDO regulator will be
current limited until the short-circuit condition is removed
from the output or LDO regulator package power dissipation exceeds the device thermal limit.
Channel 2 Thermal Protection
The AAT2689 LDO has an internal thermal protection
circuit which will turn on when the device die temperature exceeds 150°C. The internal thermal protection
circuit will actively turn off the LDO regulator output
pass device to prevent the possibility of over temperature damage. The LDO regulator output will remain in a
shutdown state until the internal die temperature falls
back below the 150°C trip point. The combination and
interaction between the short circuit and thermal protection systems allows the LDO regulator to withstand
indefinite short-circuit conditions without sustaining permanent damage.
14
The AAT2689 is designed to maintain output voltage
regulation and stability under operational no load conditions. This is an important characteristic for applications
where the output current may drop to zero.
Channel 2 Reverse Output-to-Input
Voltage Conditions and Protection
Thermal Calculations
There are three types of losses associated with the
AAT2689 step-down converter: switching losses, conduction losses, and quiescent current losses. Conduction
losses are associated with the RDS(ON) characteristics of
the power output switching devices. Switching losses are
dominated by the gate charge of the power output
switching devices. At full load, assuming continuous conduction mode (CCM), a simplified form of the synchronous step-down converter and LDO losses is given by:
PTOTAL =
IOUT12 · (RDS(ON)H · VOUT1 + RDS(ON)L · [VIN1 - VOUT1])
VIN1
+ (tSW · FS · IOUT1 + IQ1) · VIN1 + (VIN2 - VOUT2) · IOUT2
IQ1 and IQ2 are the step-down converter and LDO quiescent currents respectively. The term tSW is used to estimate the full load step-down converter switching losses.

AAT2689
PMIC Solution for 12V Adapter Systems
with 2-Output High Performance Step-Down Converters
For asynchronous step-down converter operation, the
power dissipation is only in the internal high side MOSFET
during the on time. When the switch is off, the power
dissipates on the external Schottky diode. Total package
loss for AAT2689 reduces to the following equation:
PTOTAL = IOUT12 · RDS(ON)H · D + (tSW · FS · IOUT1 + IQ1) · VIN1 + (VIN2 - VOUT2) · IOUT2
where D =
VOUT
is the duty cycle.

4.
Since RDS(ON), quiescent current, and switching losses all
vary with input voltage, the total losses should be investigated over the complete input voltage range.
Given the total losses, the maximum junction temperature can be derived from the θJA for the TDFN34-16
package, which is 50°C/W.

6.
TJ(MAX) = PTOTAL · θJA + TAMB
Layout Considerations
The suggested PCB layout for the AAT2689 is shown in
Figures 4, 5, and 6. The following guidelines should be
used to help ensure a proper layout.
1.
The power input capacitors (C1 and C15) should be
connected as close as possible to high voltage input
pin (IN1) and power ground.
7.
8.
C1, L1, D2, C9 and C11 should be placed as close as
possible to minimize any parasitic inductance in the
switched current path which generates a large voltage spike during the switching interval. The connection of inductor to switching node should be as short
as possible.
The feedback trace or FB1 pin should be separated
from any power trace and connected as close as possible to the load point. Sensing along a high-current
load trace will degrade DC load regulation.
The resistance of the trace from the load returns to
PGND should be kept to a minimum. This will help to
minimize any error in DC regulation due to differences in the potential of the internal signal ground
and the power ground.
Connect unused signal pins to ground to avoid
unwanted noise coupling.
The critical small signal components include feedback components, and compensation components
should be placed close to the FB1 and COMP1 pins.
The feedback resistors should be located as close as
possible to the FB1 pin with its ground tied straight
to the signal ground plane which is separated from
power ground plane.
C7 should be connected close to the RS1 and OS1
pins, while R2 should be connected directly to the
output pin of the inductor. For the best current limit
performance, C7 and R2 should be placed on the bottom layer to avoid noise coupling from the inductor.
For good thermal coupling, PCB vias are required
from exposed pad 1 (EP1) to the bottom ground
plane and from exposed pad 2 (EP2) to the bottom
VIN plane.
