H34063AS
DC-TO-DC CONVERTER INTEGRATE CIRCUIT DEVICES
Description
The H34063AS 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.
