Overview

The 173010378 is a highly integrated MagI3C Power Module designed as a high-efficiency replacement for traditional 3-pin linear regulators. It provides a fixed 3.3V output at up to 1A from an input voltage range of 7V to 28V, featuring integrated capacitors and an inductor in a compact 3-SIP through-hole package.

Why Choose This Part

The module simplifies PCB design by integrating the power stage and passive components into a single SIP package that occupies only 11.6mm x 8.5mm of board space. It provides robust protection with cycle-by-cycle current limiting, thermal shutdown, and short-circuit protection while maintaining a low 75uA typical quiescent current.

Applications

Point-of-Load Regulation
Efficiently stepping down 12V or 24V industrial rails to 3.3V for microcontrollers and sensors.
Linear Regulator Replacement
Drop-in upgrade for TO-220 LDOs to eliminate bulky heat sinks and improve thermal performance.
Battery Powered Systems
Extending battery life in portable commercial devices by utilizing pulse skipping at light loads and 87 percent peak efficiency.
