MC34063EBD-TR

MC34063EBD-TR is a monolithic control circuit that delivers the main functions for DC to DC voltage converting. This device contains an internal temperature compensated reference, comparator, duty cycle controlled oscillator with an active current limit circuit, driver and high current output switch. The output voltage is adjustable through two external resistors with a 2% reference accuracy. Employing a minimum number of external components, it is designed for step-down, step-up and voltage inverting applications.
