Overview
The CS5112YDWFR24G is an AC-DC offline switching controller/regulator manufactured by onsemi. It integrates a 1.4 A switching regulator with a 5.0 V, 100 mA linear regulator. The device includes essential control features such as a watchdog timer, RESET output, and ENABLE functionality. Designed for robust power supply applications, it operates within standard industrial temperature ranges and utilizes surface-mount packaging for efficient circuit board integration.
Feature Summary
- Integrates a high-current 1.4 A switching regulator with a dedicated 5.0 V, 100 mA linear regulator for auxiliary power.
- Includes built-in system management features comprising a watchdog timer, RESET signal generation, and an ENABLE pin for control.
Applications
- Offline AC-DC power supplies
- Switching regulator circuits requiring integrated control logic
- Systems needing auxiliary 5V rail generation
Procurement Notes
Verify the specific suffix 'YDWFR24G' against the official onsemi datasheet to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when an integrated solution combining a primary switching regulator with a secondary linear regulator is required. It is suitable for designs needing onboard watchdog and reset capabilities without external discrete components. Consider its 1.4 A output capability and 5.0 V auxiliary rail when sizing downstream loads.
Part Context
The CS5112 belongs to onsemi's family of AC-DC offline switching controllers. This series is designed for cost-effective power conversion solutions. The YDWFR24G variant specifically denotes the package type and reel configuration, aligning with standard surface-mount manufacturing processes for high-volume production.
Replacement Considerations
The CS5111 is listed as a similar part in public documentation. Verify electrical parameters and pinout compatibility before substitution. No other direct substitutes are confirmed in the provided source material.
