The APW34063 is a monolithic control circuit con-
taining the primary functions required for DC-to-DC
converters. This device consists of an internal tem-
perature compensated reference, comparator, con-
trolled 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 ap-
plications with a minimum number of external
components.
