CS5171ED8

Overview

The CS5171ED8 is a switching voltage regulator manufactured by onsemi, designed as a high-efficiency boost converter. It features an integrated 1.5 A power switch and operates at a fixed switching frequency of 280 kHz. The device supports a wide input voltage range from 2.7 V to 30 V, allowing flexibility in various power supply configurations. It utilizes current-mode architecture for excellent load and line regulation. The component is housed in an 8-pin SOIC package (PDSO8) with a lead-free finish.

Feature Summary

Integrates a 1.5 A power switch for compact design
Utilizes current-mode control architecture for stable regulation
Supports multiple topologies including boost, flyback, forward, and SEPIC

Applications

Portable electronics power supplies
Battery-powered devices requiring voltage step-up
Industrial control systems
Automotive electronics applications

Procurement Notes

Verify the specific suffix 'ED8' against the official onsemi datasheet to confirm pinout and electrical specifications. Ensure compatibility with the required 280 kHz switching frequency and 1.5 A current rating for the target application. Check for RoHS compliance status if environmental regulations apply to the end product.

Selection Notes

Select this component when a fixed 280 kHz boost regulator with 1.5 A capability is required. Consider the NCV5171 variant if automotive qualification is necessary. Evaluate the CS5174ED8 if a higher 560 kHz switching frequency is preferred for smaller passive components.

Part Context

The CS5171ED8 belongs to the CS5171/2/3/4 family of switching regulators. This series offers flexibility in power supply design by supporting various converter topologies beyond standard boost conversion. The family shares similar control architectures but differs in switching frequencies and specific feature sets.

Replacement Considerations

NCV5171GD8G: Automotive qualified version with identical electrical characteristics. CS5174ED8: Higher switching frequency (560 kHz) option within the same family.
