CS5173GD8G

Overview

The CS5173GD8G is a monolithic switching regulator IC from onsemi, designed for high-efficiency power conversion. It supports multiple topologies including boost, buck, flyback, forward, and SEPIC configurations. The device features an adjustable output voltage range starting at 1.28V, with a maximum switch voltage rating of 40V. It delivers a continuous switch current of 1.5A and operates at a fixed switching frequency of 560kHz. The input voltage range spans from 2.7V to 30V. Packaged in an 8-SOIC surface-mount case, it is rated for junction temperatures between 0°C and 125°C.

Feature Summary

Supports versatile power conversion topologies including boost, buck, flyback, forward, and SEPIC within a single integrated circuit.

Applications

Battery-powered portable devices requiring efficient voltage step-up or regulation
Industrial control systems utilizing isolated or non-isolated DC-DC conversion
Embedded systems needing flexible input voltage ranges up to 30V

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Validate package marking against official datasheet specifications to prevent counterfeit substitution. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when design requirements demand a single IC solution for multiple converter topologies. Consider the 1.5A switch current limit and 40V voltage rating for appropriate load matching. Evaluate thermal management needs given the 125°C maximum junction temperature rating in the SOIC-8 package.

Part Context

This part belongs to the CS517x series of switching regulators by onsemi. It shares architectural similarities with other members like the CS5171 and CS5172, offering configurable operation modes.
