Bipolar IC
For Switching Power Supply Control
s Description
The FA7630CP(E) is dual channel PWM-type switching power
supply control IC.
This IC can drive Pch-MOSFET directly and is optimum for
large power DC-DC converter.
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
Dual channel PWM-type switching power supply control
±2.6% (VREF) and ±3% (VB) reference voltage
Low voltage operation (Vcc: 5 to 20V)
Drive circuit for connecting a Pch-MOSFET
Overload cutoff circuit with timer latch circuit
Soft start circuit
Undervoltage lockout function (UVLO)
Pulse-by-pulse overcurrent limiting function
Output ON/OFF control function for each channel
Master-slave synchronized operation without external
components
Maximum operating frequency is 500kHz
