MC34063ABD-TR

MC34063ABD-TR is a MC34063A series monolithic control circuit which delivers the main functions for DC-DC voltage converting. The device contains an internal temperature compensated reference, comparator, duty cycle controlled oscillator with an active current limit circuit, driver and high current output switch. Output voltage is adjustable through two external resistors with a 2% reference accuracy. Employing a minimum number of external components, this device is designed for step-down, step-up and voltage inverting applications.
