Overview

The MC33063AVP is a versatile monolithic switching regulator subsystem designed for DC-to-DC conversion in step-up, step-down, and voltage-inverting configurations. It operates over a wide input range of 3V to 40V and features an internal temperature-compensated reference, a comparator, and a high-current output switch capable of handling up to 1.5A.

Why Choose This Part

This regulator is highly flexible, supporting three different topologies (Buck, Boost, Inverting) with a single IC. It features built-in current limiting and a precision 2% reference, while its PDIP-8 package makes it ideal for through-hole prototyping and robust industrial environments.

Applications

Battery-Powered Step-Up Converters
Boosting low-voltage battery rails to 5V or 12V for peripheral sensors and actuators.
Negative Voltage Generation
Creating bipolar power rails from a single positive input for operational amplifier stages.
Automotive Point-of-Load Regulation
Regulating 12V or 24V vehicle battery power down to logic levels using its AEC-Q100 qualified architecture.
High-Efficiency Buck Regulation
Efficiently stepping down 24V industrial bus voltages to 5V with minimal external components.

Getting Started

To design a circuit, use the timing capacitor (CT) to set the oscillator frequency and a sense resistor to establish the peak current limit. Ensure proper thermal management of the PDIP-8 package when switching near the 1.5A peak limit, and consult the datasheet for the specific external diode and inductor values required for your chosen topology.
