Bipolar IC

For Switching Power Supply Control

F_FAA₅₃₀5_1B3_P(0_N)1BP(N)

■ Description

■ Dimensions, mm

The FA5301BP(N) is a bipolar IC containing basic circuits

necessary for PWM-type switching power supply control.

This IC switches an external transistor according to external

Á SOP-16

synchronizing pulses.

■ Features

• External synchronization input terminal

• Wide supply voltage range (VCC =7 to 22V)

• Open-collector output
