Product overview

Description

The MC34063A/E series is a 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, the MC34063A/E device series is designed for step-down, step-up and voltage-inverting applications.
  • All features

    • Output switch current in excess of 1.5 A
    • 2 % reference accuracy
    • Low quiescent current: 2.5 mA (typ.)
    • Operating from 3 V to 40 V
    • Frequency operation to 100 kHz
    • Active current limiting
