HSMC Product Specification

H34063AP / H34063AS

DC-TO-DC CONVERTER INTEGRATE CIRCUIT DEVICES

Description

The H34063A Series is a monolithic control circuit containing the primary functions

required for DC-to-DC converters. These devices consist of an internal temperature

compensated reference, comparator, controlled duty cycle oscillator with an active

current limit circuit, driver and high current output switch. This series was

specifically by Hi-Sincerity Microelectronics Corp.
