TECHNICAL DATA
KIA34063A/AF
BIPOLAR LINEAR INTEGRATED CIRCUIT
DC/DC Converter Controller
The KIA34063A/AF series is a monolithic control circuit
containing the primary functions required for DC-to-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.
