A34063A
DC-DC CONVERTER CONTROL CIRCUITS
DESCRIPTION
FEATURES
The A34063A 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-down and step-up and
voltage-inverting applications with a minimum
number of external components.
Operation from 3.0V to 40V input Low standby current Current limiting Output switch current up to 1.
