AP1601

Step-Up DC/DC Converter

Features

General Description

-A Guaranteed Start-Up from less than 0.9 V.

-High Efficiency.

The AP1601 is a high efficiency step-up DC/DC

converter for applications using 1 to 4 NiMH battery

cells. Only three external components are required

to deliver a fixed output voltage of 3.3V or 5V. The

AP1601 starts up from less than 0.9V input with

1mA load. Pulse Frequency Modulation scheme

brings optimized performance for applications with

light output loading and low input voltages. The

output ripple and noise are lower compared with the

circuits operating in PSM mode.

-Low Quiescent Current.

-Less Number of External Components needed.

-Low Ripple and Low Noise.

-Space Saving Packages: MSOP-8L and

MSOP-10L.

Applications

The PFM control circuit operating in 100KHz (max.)

switching rate results in smaller passive

components. The space saving MSOP packages

make the AP1601 an ideal choice of DC/DC

converter for space conscious applications, like

pagers, electronic cameras, and wireless

microphones.

-Pagers.

-Cameras.

-Wireless Microphones.

-Pocket Organizers.

-Battery Backup Suppliers.

-Portable Instruments.

Name

Description

Use a resistor network to set the output

voltage from +2.0V to +5.5V.

OUT

GND

SHDN

LBI

LBO

REF

If FB=Vout, Vout=3.3V fix voltage

FB=GND, Vout=5V fix voltage

Low-Battery Comparator Input. Internally set

to trip at +1.30V.

LBI

Open-Drain Low-Battery Comparator Output.

MSOP-8L

Connect LBO to OUT through a 100kΩ

resistor. Output is low when V_LBIis <1.2V.

LBO

LBO is high impedance during shutdown.

1.2V Reference Voltage. Bypass with a 0.1µF

capacitor.

OUT

REF

N-Channel and P-Channel Power MOSFET

Drain

MSOP-10L

GND Ground

Shutdown Input. Drive high (>80% of V_OUT) for

operating mode. Drive low (<20% of V_OUT) for

shutdown mode. Connect to OUT for normal

operation.

SHDN

Current-Limit Select Input. CLSEL = OUT sets

CLSEL the current limit to 0.8A. CLSEL = GND sets

the current limit to 0.4A.
