General Description
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.)

components. The space saving MSOP packages
make the AP1601 an ideal choice of DC/DC
converter for space conscious applications, like
pagers,
electronic
cameras,
microphones.

Pin Descriptions
Name
Use a resistor network to set the output
voltage from +2.0V to +5.5V.
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.
Open-Drain Low-Battery Comparator Output.
