Large Current External FET Controller Type Switching Regulators

●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
