Description

The APW34063 is a monolithic control circuit containing the primary functions required for DC-to-DC converters. This device consists of an internal temperature
compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. This device was specifically designed to be incorporated in Step-Down and Step-Up and Voltage-Inverting applications with a minimum number of external components.
