AP1601

STEP-UP DC/DC CONVERTER

General Description

Features

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.

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.
