Switching Regulator (Controller type)
BD63536FJ
No.09028EAT09
●Description
The BD63536FJ is a gate direct drive switching regulator operational at a power supply voltage from 3V. This regulator uses
a compact package SOP-J8 and operates as a switching regulator for the voltage control type of step-down DC/DC
converter. The regulator features reliable design with 1% reference voltage accuracy, built-in current limit function (4%),
and a variety of built-in protection circuits.
●Features
1) Gate direct drive available (External Pch FET, Vcc-5.4V)
2) Built-in current limit function (150mV4%)
3) Built-in gate-off function
4) Error amplifier reference voltage (1.25V1%)
5) Built-in soft start
6) 2.5V regulator output
7) External oscillation frequency variable
8) Built-in thermal shutdown circuit
●Applications
Laser beam printers, MFPs, PPCs, etc.
●Absolute maximum ratings (Ta25C)
