CS5171EDR8G

Overview

The CS5171EDR8G is a high-efficiency boost switching regulator manufactured by onsemi. It supports an input voltage range of 2.7 V to 30 V and delivers a continuous output current of 1.5 A. The device operates at selectable switching frequencies of 280 kHz or 560 kHz, enabling optimization for efficiency or component size. It features adjustable output voltage starting from 1.28 V and includes integrated soft-start functionality. The IC is housed in an 8-SOIC surface-mount package.

Feature Summary

Supports multiple converter topologies including boost, buck, flyback, forward, and SEPIC configurations
Integrates current-mode control with programmable switching frequency selection
Includes internal soft-start circuitry to limit inrush current during startup

Applications

Battery-powered portable electronics requiring voltage step-up
Industrial control systems utilizing single-rail power distribution
Automotive infotainment and sensor modules operating within wide input ranges

Procurement Notes

Verify the specific suffix 'EDR8G' against the official datasheet to confirm pinout compatibility and lead-free status. Confirm that the 280 kHz/560 kHz frequency selection matches the target application requirements. Check for end-of-life notices as availability may be restricted.

Selection Notes

Select this component when a versatile single-inductor solution is required for mixed topology designs. Ensure the external inductor can handle the peak currents associated with the 1.5 A output rating. Verify that the desired switching frequency aligns with the available passive component values for the target output voltage.

Part Context

This part belongs to the CS5171/CS5173 family of regulators designed for flexible power conversion. It shares architectural similarities with the NCP5173 but offers distinct frequency options. The series targets applications needing compact footprints and high efficiency across varying load conditions.
