ON Semiconductor MC34063A/MC33063A/NCV33063A 1.5 A Switching Regulator Datasheet
The MC34063A Series is a monolithic control circuit containing the primary functions required for DC-to-DC converters. These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. This series was specifically designed to be incorporated in Step-Down and Step-Up and Voltage-Inverting applications with a minimum number of external components.
The document provides detailed electrical characteristics, maximum ratings, and application circuit diagrams for step-up, step-down, and voltage inverting converters. It includes test results for line regulation, load regulation, efficiency, and output ripple under various conditions, as well as package dimensions for SOIC-8 and PDIP-8 packages.
