Bipolar IC
For Switching Power Supply Control
s Description
The FA7622CP(E) is a DC-DC converter IC that can directly
drive a power MOSFET. This IC has all the necessary
protection functions for a power MOSFET. It is optimum for a
portable equipment power supply which uses low-voltage input
to output comparably large power.
s Features
Drive circuit for connecting a power MOSFET
(Io =
±600mA)
Built-in voltage step-up circuit to drive a power MOSFET
gate: A converter circuit requires only an N-channel power
MOSFET.
Dual control circuit
Overcurrent limiting circuit
Overload cutoff circuit with timer and latch circuit
ON/OFF control pin
Wide operating range: 3.6 to 28V
High-frequency operation: up to 1MHz
20-pin package (DIP/SSOP)
s Applications
Battery power supply for portable equipment
