General Description
The BD63536FJ is a gate direct drive switching
regulator operating at a power supply voltage from 3V
to 30V. 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.
