HSMC Product Specification
H34063AP
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.
