GENERAL DESCRIPTION
The TC33063A Series ia a monolithic control circuit
containing the primary functions required for DC/DC con-
verters. 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 Volt-
age–Inverting applications with a minimum number of exter-
nal components.
