1 General Description
2 Key Features
The AS1330 is a synchronous, low voltage, high
efficiency DC-DC boost converter running at a constant
frequency of 4MHz. This very high oscillator frequency
!
Input Voltage Range: 0.6V to 3.0V
!
Adjustable Output Voltage Range: 1.8V to 3.3V
allows the usage of a very a small and low profile
inductor with only 470nH. This results in a board space
requirement of only 43mm² for the complete solutions
including all external components.
AS1330 generates an output voltage between 1.8 and
3.3V from input voltages down to 0.6V. Therefore it is
ideal for application powered by a single cell battery.
AS1330 provides an output current of 150mA @ 3.3V
from a single cell.
To support high efficiency across the entire load range
the AS1330 is equipped with a synchronous rectifier and
features a power save mode for light loads.
To avoid harmful deep discharge of the battery during
shutdown the AS1330 is equipped with an output
disconnect function.
AS1330 can either monitor the battery voltage (Sense
pin) or report the status of the output voltage (POK).

Description
Sense Input. Represents the input for the Power-OK behaviour. This input can be
used to supervise the input or the output voltage via a resistor divider. If connected
to GND the POK output is related to VOUT.
Feedback Pin. Feedback input to the gm error amplifier. Connect a resistor divider
tap to this pin. The output voltage can be adjusted from 1.8 to 3.3V by: VOUT =
0.8V[1 + (R1/R2)]
If the fixed output voltage version ist used, connect this pin to VOUT.
Active-High Enable Input. A logic LOW reduces the supply current to < 1µA.
Connect to pin VIN for normal operation.
Power-OK Output. Active-High, open-drain output indicates an out-of-regulation
condition. Connect a 100kΩ pull-up resistor to pin OUT for logic levels. Leave this
pin unconnected if the Power-OK feature is not used.
Low Level:
High Level:
Signal and Power Ground. Provide a short, direct PCB path between this pin and
the negative side of the output capacitor(s).
Switch Pin. Connect an inductor between this pin and VIN. Keep the PCB trace
lengths as short and wide as is practical to reduce EMI and voltage overshoot. If
the inductor current falls to zero, or pin EN is low, an internal 100Ω anti-ringing
switch is connected from this pin to VIN to minimize EMI.
Note: An optional Schottky diode can be connected between this pin and VOUT.
Output Voltage. Bias is derived from VOUT when VOUT exceeds VIN. PCB trace
length from VOUT to the output filter capacitor(s) should be as short and wide as is
practical.
Input Voltage. The AS1330 gets its start-up bias from VIN unless VOUT exceeds
VIN, in which case the bias is derived from VOUT. Thus, once started, operation is
completely independent from VIN. Operation is only limited by the output power
level and the internal series resistance of the supply.
Exposed Pad. The exposed pad must be connected to GND. Ensure a good
connection to the PCB to achieve optimal thermal performance.

8 Detailed Description
The AS1330 can operate from a single-cell input voltage (VIN) below 1V, and features fixed frequency (4MHz) and current mode PWM control for exceptional line- and load-regulation. With low RDS(ON) and gate charge internal NMOS
and PMOS switches, the device maintains high-efficiency from light to heavy loads.
Modern portable devices frequently spend extended time in low-power or standby modes, switching to high powerdrain only when certain functions are enabled. The AS1330 is ideal for portable devices since it maintain high-power
conversion efficiency over a wide output power range, thus increasing battery life in these types of devices.
In addition to high-efficiency at moderate and heavy loads, the AS1330 includes an automatic powersave mode that
improves efficiency of the power converter at light loads. The powersave mode is initiated if the output load current
falls below a factory programmed threshold.

Low-Voltage Start-Up
The AS1330 requires VIN of only 0.85V (typ) or higher to start up. The low-voltage start-up circuitry controls the internal
NMOS switch up to a maximum peak inductor current of 650mA (typ), with 1.5ms (approx.) off-time during start-up,
allowing the devices to start up into an output load.
With a VOUT > 1.65V, the start-up circuitry is disabled and normal fixed-frequency PWM operation is initiated. In this
mode, the AS1330 operates independent of VIN, allowing extended operating time as the battery can drop to several
tenths of a volt without affecting output regulation. The limiting factor for the application is the ability of the battery to
supply sufficient energy to the output.

Low-Noise Fixed-Frequency Operation
Oscillator
The AS1330 switching frequency is internally fixed at 4MHz allowing the use of very small external components.
Current Sensing
A signal representing the internal NMOS-switch current is summed with the slope compensator. The summed signal is
compared to the error amplifier output to provide a peak current control command for the PWM. Peak switch current is
limited to approximately 650mA independent of VIN or VOUT.
Zero Current Comparator
The zero current comparator monitors the inductor current to the output and shuts off the PMOS synchronous rectifier
once this current drops to 20mA (approx.). This prevents the inductor current from reversing polarity and results in
improved converter efficiency at light loads.
Anti-Ringing Control
Anti-ringing control circuitry prevents high-frequency ringing on pin SW as the inductor current approaches zero. This
is accomplished by damping the resonant circuit formed by the inductor and the capacitance on pin SW (CSW).
Powersave Operation
In light load conditions, the integrated powersave feature removes power from all circuitry not required to monitor
VOUT. When VOUT has dropped approximately 1% from nominal, the device powers up and begins normal PWM operation.
C2 recharges, causing the AS1330 to re-enter powersave mode as long as the output load remains below the powersave threshold. The frequency of this intermittent PWM is proportional to load current; i.e., as the load current drops
further below the powersave threshold, the AS1330 turns on less frequently. When the load current increases above
the powersave threshold, the AS1330 will resume continuous, seamless PWM operation.
Notes:
1. An optional capacitor (CFF) between pins VOUT and FB in some applications can reduce VOUTp-p ripple and input
quiescent current during powersave mode. Typical values for CFF range from 15 to 220pF.
2. In powersave mode the AS1330 draws only 30µA from the output capacitor(s), greatly improving converter efficiency.
Shutdown
When pin EN is low the AS1330 is switched off and <1µA current is drawn from the battery; when pin EN is high the
device is switched on. If EN is driven from a logic-level output, the logic high-level (on) should be referenced to VOUT to
avoid intermittently switching the device on.
In shutdown the battery input is disconnected from the output.
Thermal Overload Protection
To prevent the AS1330 from short-term misuse and overload conditions the chip includes a thermal overload
protection. To block the normal operation mode the device is turning the PFET and the NFET off in PWM mode as
soon as the junction temperature exceeds 150°C. To resume the normal operation the temperature has to drop below
140°C.
Note: Continuing operation in thermal overload conditions may damage the device and is considered bad practice.

9 Application Information
The AS1330 is ideal for space critical applications where ultra-small size is critical as in medical diagnostic equipment,
hand-held instruments, digital cameras, MP3 players, GPS receivers, and PC or Memory cards.
Along with Figure 1 on page 1, Figure 20, Figure 21 and Figure 22 on page 11depict a few of the many applications for
which the AS1330 converters are perfectly suited.
Adjustable Output Voltage
The integrated error amplifier is an internally compensated trans-conductance (gm) type (current output). The internal
0.8V reference voltage is compared to the voltage at pin FB to generate an error signal at the output of the error amplifier. A voltage divider from VOUT to GND programs the output voltage from 1.8 to 3.0V via pin FB as:
VOUT = 0.8V(1 + (R1/R2))
(EQ 1)
Sense Function
The AS1330 offers a sense function for monitoring a voltage (e.g.: the battery voltage). The sense function can work in
three different modes:
- SENSE to GND: The POK is related to VOUT (see Figure 22 on page 11).
- SENSE to VIN: If the pin SENSE is directly connected to pin VIN, the internal reference voltage (0.8V) is used to
compare it with VIN. The POK goes high when the voltage on SENSE is above 0.8V and low when the voltage on
SENSE is below 0.8V (see Figure 21 on page 11).
- SENSE to a voltage divider: With the voltage divider the threshold voltage on which the POK reacts can be set. If
the monitored voltage is higher then the user set threshold voltage the POK is high, when the monitored voltage
is lower the POK goes low (see Figure 20). The threshold voltage can be set with the following equation:
Vthreshold = 0.8V(1 + (RIN1/RIN2))

Component Selection
Only three power components are required to complete the design of the boost converter, except the additional two
resistors for the voltage divider to set VOUT. The high operating frequency and low peak currents of the AS1330 allow
the use of low value, low profile inductors and tiny external ceramic capacitors.
Inductor Selection
The inductor should have low ESR to reduce the I²R power losses, and must be able to handle the peak inductor
current without saturating. High-frequency ferrite core inductor materials reduce frequency dependent power losses
compared to less expensive powdered iron types, which result in improved converter efficiency.
A 1µH inductor with a >850mA current rating and low DCR is recommended. For applications where radiated noise is
a concern, a toroidal or shielded inductor can be used.
Capacitor Selection
A 4.7µF capacitor is recommended for C1 and for C2. Small-sized ceramic capacitors are recommended. X5R and
X7R ceramic capacitors are recommended as they retain capacitance over wide ranges of voltages and temperatures.
Output Capacitor Selection
Low ESR capacitors should be used to minimize VOUT ripple. Multi-layer ceramic capacitors are recommended since
they have extremely low ESR and are available in small footprints. Up to 10µF output capacitor is sufficient for most
applications. Larger values up to 22µF may be used to obtain extremely low output voltage ripple and improve transient response.
An additional phase lead capacitor may be required with output capacitors larger than 10µF to maintain acceptable
phase margin. X5R and X7R dielectric materials are recommended due to their ability to maintain capacitance over
wide voltage and temperature ranges.
Input Capacitor Selection
Low ESR input capacitors reduce input switching noise and reduce the peak current drawn from the battery. Ceramic
capacitors are recommended for input decoupling and should be located as close to the device as is practical. A 4.7µF
input capacitor is sufficient for most applications. Larger values may be used without limitations.

Diode Selection
A Schottky diode should be used to carry the output current for the time it takes the PMOS synchronous rectifier to
switch on. For VOUT > 3.0V a schottky diode is mandatory, for VOUT ≤ 3.0V a it is optional, although using one will
increase device efficiency by 2 to 3%. On one hand the schottky diode reduces the overshoot on the output signal but
on the other hand the output disconnect function is no longer working.
Note: Do not use ordinary rectifier diodes, since the slow recovery times will compromise efficiency.
