DC-DC CONVERTER
Description
The BM34063 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.
