AP1602

Step-Up DC/DC Converter

Features

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

-High Efficiency.

-Low Quiescent Current.

-Less Number of External Components needed.

-Low Ripple and Low Noise.

-Space Saving Packages: SOT89-5

General Description

The AP1602 is a high efficiency step-up DC/DC

converter for applications using 1 to 2 NiMH battery

cells. Only three external components are required

to deliver a fixed output voltage of 3.3V. The

AP1602 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.

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

switching rate results in smaller passive

components. The space saving SOT89-5 packages

make the AP1602 an ideal choice of DC/DC

converter for space conscious applications, like

pagers, electronic cameras, and wireless

microphones.

Applications

-Pagers.

-Cameras.

-Wireless Microphones.

-Pocket Organizers.

-Battery Backup Suppliers.

-Portable Instruments.
