TIMC33063ADR
Overview
The MC33063ADR is a versatile monolithic control circuit containing the primary functions required for DC-to-DC converters. It 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 handling up to 1.5A.
Why Choose This Part
This regulator is highly flexible, supporting buck, boost, and inverting topologies with a wide input voltage range from 3V to 40V. Its integrated 1.5A switch reduces external component count, while the 2% precision internal reference ensures stable output regulation.
Applications
Key Specifications
Getting Started
Design begins by calculating the timing capacitor for the 100kHz oscillator and selecting an inductor based on the peak switch current. Engineers should utilize the equations provided in the datasheet to set the adjustable output via a resistor divider and implement the short-circuit current limiting using a sense resistor at the Ipk pin.
