KIA34063A/AF

BIPOLAR LINEAR INTEGRATED CIRCUIT

Revision No : 2

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.

FEATURES

・Operation from 3.0V to 40V input.

・Low Standby Current.

・Current Limiting.

・Output Switch Current to 1.5A.

・Output Voltage Adjustable.

・Frequency Operation to 100kHz.

・Precision 2% Reference.
