DC-TO-DC CONVERTER INTEGRATE CIRCUIT DEVICES

Description

The H34063AP 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.
