Overview
The CS5173GD8 is a switching voltage regulator manufactured by onsemi, designed for high-efficiency boost applications. It supports an input voltage range from 2.7V to 30V and delivers a maximum switch current of 1.5A. The device features adjustable output voltage starting at a minimum of 1.28V, with a maximum switch voltage rating of 40V. Operating at a fixed frequency of 560kHz, it utilizes a single positive output configuration. The component is housed in an 8-SOIC package (0.154" width) and operates within a junction temperature range of 0°C to 125°C.
Feature Summary
- Supports multiple converter topologies including boost, buck, flyback, forward, and SEPIC configurations.
- Integrates current-mode control for efficient power regulation.
- Features adjustable output voltage capability for flexible design implementation.
Applications
- Portable electronic devices requiring step-up voltage conversion
- Battery-powered systems needing regulated higher voltage rails
- General-purpose DC-DC conversion in industrial equipment
Procurement Notes
Verify the specific suffix 'GD8' against official documentation, as datasheets primarily reference 'EDR8G'. Confirm RoHS compliance status, as some variants are marked non-compliant. Check for obsolescence notices, as this family has been subject to production discontinuation. Ensure the supplier provides valid traceability for the SOIC-8 package variant.
Selection Notes
Select this component when a robust boost regulator with wide input voltage tolerance is required. Consider the 1.5A current limit and 560kHz switching frequency for size constraints. Evaluate thermal performance within the 0°C to 125°C operating range. Verify that the 8-SOIC package fits the PCB layout requirements compared to tape-and-reel alternatives.
Part Context
The CS5173 belongs to a family of 1.5A boost regulators from onsemi, often grouped with parts like CS5171 and NCP5173. These devices share similar electrical characteristics but may differ in packaging or specific feature sets. The CS5173 series is designed for offline and online switching applications requiring high efficiency.
Replacement Considerations
Official substitutes include CS5173EDR8G and CS5173GD8G. Cross-reference pinouts and thermal specifications before replacement. Note that some variants may have different RoHS compliance statuses.
