DC-DC CONVERTER CONTROL CIRCUITS
DESCRIPTION
FEATURES
The A7463 series is a monolithic control circuit
containing the primary functions required for DC-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 designed to be
incorporated in step-do.
