CS5173GDR8G

Overview

The CS5173GDR8G is a switching regulator IC manufactured by onsemi, designed as a high-efficiency boost converter. It supports an input voltage range from 2.7 V to 30 V and delivers a maximum switch current of 1.5 A. The device operates at selectable switching frequencies of 280 kHz or 560 kHz. It is housed in an 8-pin SOIC narrow body package with a junction temperature range of 0°C to 125°C.

Feature Summary

• Integrated current-mode control architecture for efficient power conversion
• Selectable switching frequency options to optimize external component size
• Built-in protection mechanisms including thermal shutdown

Applications

• Portable battery-powered equipment
• Automotive electronics systems
• Industrial control applications

Procurement Notes

Verify the specific suffix GDR8G against the official datasheet to confirm pinout and RoHS compliance status. Check obsolescence notices as this family may have end-of-life notifications. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing procurement orders.

Selection Notes

Select this component when a non-synchronous boost topology is required for cost-sensitive designs. The 1.5 A output current capability suits moderate power loads. Consider the 280 kHz/560 kHz frequency selection based on inductor size constraints and electromagnetic interference requirements in the target application environment.

Part Context

This part belongs to the CS517x series of boost regulators from onsemi. It shares functional similarities with the CS5171 and CS5174 models but differs in specific electrical characteristics and pin configurations. The series is designed for general-purpose DC-DC conversion tasks requiring reliable performance in compact form factors.

Replacement Considerations

NCP5173 is a pin-compatible upgrade within the same manufacturer's portfolio offering enhanced specifications.
