CS5173ED8G

Overview

The CS5173ED8G is a high-efficiency boost switching regulator manufactured by onsemi, designed for applications requiring a 1.5 A output current. It operates with an input voltage range of 2.7 V to 30 V and provides an adjustable output voltage up to 40 V. The device supports fixed switching frequencies of 280 kHz or 560 kHz. It is housed in an 8-SOIC package and is qualified under the AEC-Q100 standard for automotive reliability. The component functions as a charge pump topology converter suitable for various power management needs.

Feature Summary

Supports multiple switching frequencies including 280 kHz and 560 kHz for flexible design options
Capable of delivering 1.5 A output current for high-power boost applications
Automotive qualified under AEC-Q100 standards for enhanced reliability
Operates over an extended temperature range from -40°C to +125°C

Applications

Automotive electronics systems
Industrial power supplies
General-purpose DC-DC conversion

Procurement Notes

Verify end-of-life status before procurement as discontinuance notifications may apply. Confirm RoHS compliance details through official datasheets. Ensure compatibility with existing PCB footprints for SOIC-8 packages. Validate supply chain sources against authorized distributors to avoid counterfeit components. Check for specific ordering suffixes that may affect packaging or qualification levels.

Selection Notes

Select this component when a robust boost regulator with automotive qualification is required. Consider the 1.5 A current limit and 30 V maximum input voltage constraints during circuit design. Evaluate the need for external synchronization if operating at 280 kHz or 560 kHz. Compare against similar models like CS5173EDR8G for package availability differences. Ensure thermal management strategies align with the 125°C junction temperature rating.

Part Context

The CS5173ED8G belongs to the CS5173 series of high-efficiency boost regulators from onsemi. This series is part of the broader PMIC portfolio focused on power management solutions. The device shares functional similarities with other members like CS5173EDR8G but differs in packaging configuration. It serves as a legacy component within onsemi's switching regulator lineup.
