FSP3112
GENERAL DESCRIPTION
The FSP3112 is a dual channel high efficiency
monolithic synchronous step down current mode
DC-DC converter operating at 1.5MHz constant
frequency. The device integrates a main switch and a
synchronous rectifier for high efficiency without an
external Schottky diode for each of the channels. The
FSP3112 can operate from a 2.5V to 5.5V input voltage
and is ideal for powering portable equipment that runs
from a single cell lithium-Ion (Li+) battery. It can supply
600mA output current for each channel and can also
run at 100% duty cycle for low dropout operation,
extending battery life in portable system. For FSP3112,
Pulse Skipping Mode operation at light loads provides
very low output ripple voltage for noise sensitive
applications.
