Overview
The CS5172EDR8 is a switching voltage regulator manufactured by onsemi, housed in an SOIC-8 package. It operates as a boost converter with adjustable output voltage and supports up to 1.5 A output current. The device accepts an input voltage range from 2.7 V to 30 V and functions at a fixed switching frequency of 560 kHz. It is rated for operation between -40°C and +125°C.
Feature Summary
- Integrated high-efficiency boost topology for step-up power conversion
- Adjustable output voltage capability within specified limits
- Designed for surface-mount installation in compact layouts
Applications
- General DC-DC power supply circuits requiring voltage boosting
- Battery-powered systems needing higher operating voltages
- Portable electronic devices utilizing single-cell or multi-cell battery inputs
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical characteristics and package dimensions. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the component source matches the authorized distribution channels to avoid counterfeit parts. Check for any recent product change notices that may affect availability or specifications.
Selection Notes
Select this component when a non-synchronous boost converter is required for moderate current applications. Consider the fixed 560 kHz switching frequency for inductor sizing and EMI management. Evaluate the thermal performance within the SOIC-8 package for the intended load conditions. Compare against synchronous alternatives if higher efficiency at light loads is critical.
Part Context
This part belongs to the CS517x series of switching regulators from onsemi. The series includes variants such as CS5171, CS5173, and CS5174, which share similar form factors but differ in switching frequencies and output configurations. These components are designed for general-purpose power management tasks in consumer and industrial electronics.
Replacement Considerations
CS5172GDR8G is listed as a discontinued alternative. Verify compatibility with CS5174EDR8 for boost applications, noting differences in switching frequency and output current ratings. Consult official substitution guides for pin-to-pin compatibility and electrical parameter alignment.
