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.
