AAT3158 High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications
General Description
Features
The AAT3158 is a low noise, constant frequency charge
pump DC/DC converter that uses a tri-mode load switch
(1X), fractional (1.5X), and doubling (2X) conversion to
maximize efficiency for white LED applications. The
AAT3158 is capable of driving up to four LED channels at
20mA per channel from a 2.7V to 5.5V input. The current
sinks may be operated individually or in parallel for driving higher current LEDs. A low external parts count (two
1µF flying capacitors and two small 1µF capacitors at VIN
and VOUT) make this part ideally suited for small, batterypowered applications.
•VIN Range: 2.7V to 5.5V
• Fully Programmable Current with Single Wire
▪ 16 Current Levels
▪ Four Low Current Settings Down to 50µA
• Low IQ (50µA) for Low Current Mode
• Tri-Mode 1X, 1.5X, and 2X Charge Pump for Maximum
Efficiency and VF Coverage
• Drives Up to Four LED Channels
• No Inductors, Low Noise Operation
• 1MHz Constant Switching Frequency
• Small Application Circuit
• Built-In Thermal Protection
• Automatic Soft-Start

• 2.85x3mm TSOPJW-12 Package
Skyworks' S2Cwire™ (Simple Serial Control) serial digital
input is used to enable, disable, and set current for each
LED with 16 settings down to 50µA. The low current
mode supply current can be as low as 50µA to save
power.
Applications
Each output of the AAT3158 is equipped with built-in
protection for VOUT short circuit and auto disable for load
short-circuit conditions. Built-in soft-start circuitry prevents excessive inrush current during start-up. A low
current shutdown feature disconnects the load from VIN
and reduces quiescent current to less than 1µA.

Functional Description
The AAT3158 is a tri-mode load switch (1X) and high
efficiency (1.5X or 2X) charge pump device intended for
white LED backlight applications. To maximize power
conversion efficiency, an internal sensing circuit monitors the voltage required on each constant current sink
input and sets the load switch and charge pump modes
based on the input battery voltage and the current sink
input voltage. As the battery discharges over time, the
AAT3158 charge pump is enabled when any of the four
current sink inputs nears dropout. The charge pump initially starts in 1.5X mode. If the charge pump output
droops enough for any current source output to become
close to dropout, the charge pump will automatically
transition to 2X mode. The AAT3158 requires only four
external components: two 1µF ceramic capacitors for the
charge pump flying capacitors (C1 and C2), one 1µF
ceramic input capacitor (CIN), and one 0.33µF to 1µF
ceramic charge pump output capacitor (COUT).
8
The four constant current sink inputs (D1 to D4) can
drive four individual LEDs with a maximum current of
20mA each. The unused sink inputs must be connected
to VOUT; otherwise, the part will operate only in 2X charge
pump mode. The S2Cwire serial interface enables the
AAT3158 and sets the current sink magnitudes.
Constant Current Output Level Settings
The constant current sink levels for D1 to D4 are set via
the serial interface according to a logarithmic scale for
the first 12 codes, and a separate low current scale for
the last 4 codes. For the first 12 codes, each code is
approximately 1.5dB lower than the previous code. In
this manner, LED brightness appears linear with each
increasing code count. Because the inputs D1 to D4 are
true independent constant current sinks, the voltage
observed on any single given input will be determined by
the actual forward voltage (VF) for the LED being driven.

DATA SHEET
AAT3158
AAT3158 High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications
Since the input current sinks of the AAT3158 are programmable, no PWM (pulse width modulation) or additional control circuitry is needed to control LED brightness. This feature greatly reduces the burden on a
microcontroller or system IC to manage LED or display
brightness, allowing the user to “set it and forget it.”
With its high-speed serial interface (1MHz data rate),
the input sink current of the AAT3158 can be changed
successively to brighten or dim LEDs in smooth transitions (e.g., to fade-out) or in abrupt steps, giving the
user complete programmability and real-time control of
LED brightness.
The S2Cwire serial interface has flexible timing. Data can
be clocked-in at speeds greater than 1MHz, or much
slower, such as 15kHz. After data is submitted, EN/SET
is held high to latch the data. Once EN/SET has been
held in the logic high state for time TLAT, the programmed
current becomes active and the internal data register is
reset to zero. For subsequent current level programming, the number of rising edges corresponding to the
desired code must be entered on the EN/SET pin.
When EN/SET is held low for an amount of time greater
than TOFF, the AAT3158 enters into shutdown mode and
draws less than 1µA from VIN. The internal data register
is reset to zero during shutdown.
S2Cwire Serial Interface
Auto-Disable Feature
The current level magnitude is controlled by Skyworks'
Simple Serial Control (S2Cwire) serial interface. The
interface records rising edges of the EN/SET pin and
decodes them into 16 different states. The 16 current
level settings available are indicated in Table 1.

The AAT3158 is equipped with an auto-disable feature for
each LED channel. After the IC is enabled and started up,
a test current of 100µA (typical) is forced through each
sink channel. The channel will be disabled if the voltage
of that particular SINK pin does not drop to certain
threshold. This feature is very convenient for disabling an
unused channel or during an LED fail short event.
Thermal Protection
The AAT3158 has built-in thermal protection circuit that
will shut down the charge pump if the die temperature
rises above the thermal limit, as is the case during a
short circuit of the VOUT pin.

DATA SHEET
AAT3158
AAT3158 High Efficiency 1X/1.5X/2X Charge Pump for White LED Applications
Applications Information
LED Selection
Although AAT3158 is specifically intended for driving
white LEDs, the device can also be used to drive most
types of LEDs with forward voltage specifications ranging
from 2.0V to 4.7V. LED applications may include main
and sub-LCD display backlighting, camera photo-flash
applications, color (RGB) LEDs, infrared (IR) diodes for
remotes, and other loads benefiting from a controlled
output current generated from a varying input voltage.
Since the D1 to D4 input current sinks are matched with
negligible voltage dependence, the LED brightness will be
matched regardless of the specific LED forward voltage
(VF) levels. In some instances (e.g., in high-luminousoutput applications such as photo flash), it may be necessary to drive high-VF type LEDs. The low dropout current
sinks in the AAT3158 make it capable of driving LEDs
with forward voltages as high as 4.7V at full current from
an input supply as low as 3.0V. Outputs can be paralleled
to drive high-current LEDs without complication.
Device Switching Noise Performance
The AAT3158 operates at a fixed frequency of approximately 1MHz to control noise and limit harmonics that
can interfere with the RF operation of cellular telephone
handsets or other communication devices. Back-injected
noise appearing on the input pin of the charge pump is
20mV peak-to-peak, typically ten times less than inductor-based DC/DC boost converter white LED backlight
solutions. The AAT3158 soft-start feature prevents noise
transient effects associated with inrush currents during
start-up of the charge pump circuit.
Capacitor Selection
Careful selection of the four external capacitors (CIN, C1,
C2, COUT) is important because they will affect turn-on
time, output ripple, and transient performance. Optimum
performance will be obtained when low Equivalent Series
Resistance (ESR) ceramic capacitors are used; in general, low ESR may be defined as less than 100mW. A
value of 1µF for all four capacitors is a good starting
10
point when choosing capacitors. If the LED current
sources are only programmed for light current levels,
then the capacitor size may be decreased.
Capacitor Characteristics
Ceramic composition capacitors are highly recommended
over all other types of capacitors for use with the
AAT3158. Ceramic capacitors offer many advantages
over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is
lowest cost, has a smaller PCB footprint, and is nonpolarized. Low ESR ceramic capacitors help maximize
charge pump transient response. Since ceramic capacitors are non-polarized, they are not prone to incorrect
connection damage.
Equivalent Series Resistance
ESR is an important characteristic to consider when
selecting a capacitor. ESR is a resistance internal to a
capacitor that is caused by the leads, internal connections, size or area, material composition, and ambient
temperature. Capacitor ESR is typically measured in milliohms for ceramic capacitors and can range to more
than several ohms for tantalum or aluminum electrolytic
capacitors.
Ceramic Capacitor Materials
Ceramic capacitors less than 0.1µF are typically made
from NPO or C0G materials. NPO and C0G materials
typically have tight tolerance and are stable over temperature. Larger capacitor values are typically composed
of X7R, X5R, Z5U, or Y5V dielectric materials. Large
ceramic capacitors, typically greater than 2.2µF, are
often available in low-cost Y5V and Z5U dielectrics, but
capacitors greater than 1µF are typically not required for
AAT3158 applications. Capacitor area is another contributor to ESR. Capacitors that are physically large will
have a lower ESR when compared to an equivalent
material smaller capacitor. These larger devices can
improve circuit transient response when compared to an
equal value capacitor in a smaller package size.
