CS5171GDR8

Overview

The CS5171GDR8 is a positive adjustable boost switching regulator IC manufactured by onsemi. It operates with an input voltage range of 2.7 V to 30 V and delivers a maximum switch current of 1.5 A. The device features a fixed switching frequency of 280 kHz and supports output voltages from 1.28 V up to 40 V. It is housed in an 8-SOIC package (3.90 mm width) and functions within a junction temperature range of 0°C to 125°C.

Feature Summary

Supports multiple converter topologies including boost, buck-boost, flyback, forward, and SEPIC configurations.
Utilizes current-mode control for stable regulation across varying load conditions.
Provides adjustable output voltage capability via external feedback components.

Applications

Battery-powered systems requiring voltage step-up
Industrial power supply designs
Automotive electronics applications

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm RoHS compliance and lead-free packaging specifications against the official datasheet. Ensure the 8-SOIC package dimensions match design requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring a single-inductor multi-output or flexible topology solution. Compare the 280 kHz switching frequency against system noise constraints. Evaluate the 1.5 A switch current limit against peak load demands to ensure adequate headroom.

Part Context

This device belongs to the CS517x series of DC-DC controllers designed for versatile power conversion needs. It shares architectural similarities with the CS5173 and CS5174 models but differs in output polarity and specific operating parameters. The series targets cost-sensitive industrial and consumer markets.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with legacy designs if direct replacement is required.
