MC34063D
DC/DC Converter Control Circuits
DESCRIPTION
The MC34063D is a monolithic control circuit containing the primary functions required for DC-to-DC converter. This device
consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current
limit circuit, driver and high current output switch. Employing a minimum number of external components, the MC34063D is
designed for Step-Down, Step-Up and Voltage-Inverting applications.
FEATURES
¨ Operation from 3V to 40V
¨ Active Current Limiting
¨ Low Quiescent Current: 3mA
¨ Output Switch Current in Excess of 1.5A
¨ Adjustable Output Voltage
¨ Frequency Operation to 100 kHz
¨ 2% Reference Accuracy
