Overview

The MC33063ADR2G is a versatile monolithic control circuit containing the primary functions required for DC-to-DC converters. This bipolar device features an internal temperature compensated reference, a comparator, a controlled duty cycle oscillator with an active current limit circuit, a driver, and a high current output switch capable of 1.5A.

Why Choose This Part

The part is highly flexible, allowing for buck, boost, and inverting topologies with a minimal number of external components. It supports a wide input voltage range up to 40V and includes an integrated 1.5A switch, making it a cost-effective alternative to modern complex switching regulators for simpler power requirements.

Applications

Step-Down (Buck) Converters
Efficiently converting a higher input voltage down to a lower regulated output for logic or peripheral power.
Step-Up (Boost) Converters
Increasing a lower battery or bus voltage to a higher level required by specific sensors or actuators.
Voltage Inverting Converters
Generating a negative supply rail from a positive input voltage for operational amplifiers or bipolar analog circuits.
Point-of-Load Regulation
Providing local regulation in distributed power systems where space and cost are primary constraints.

Getting Started

To design with this part, consult the manufacturer's datasheet for the standard equations used to select the timing capacitor, inductor, and feedback resistors for your desired topology. Ensure the peak current does not exceed the 1.5A internal switch limit, and use a low-ESR capacitor for the output filter to minimize ripple.
