H34063BP / H34063BS
DC-to-DC Converter Integrate Circuit Devices
Description
The H34063B 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 Avantics
Microelectronics Corp.
