Description

The MC34063A/B series is a monolithic control circuit delivering the main functions for DC-DC voltage converting.
The device contains an intermal 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 the MC34063A/B devices series is designed for Step-Down, Step-Up and Voltage-Inverting applications.
