Overview
The CS51413EDR8G is a synchronous buck switching voltage regulator manufactured by onsemi. It integrates high-side and low-side power MOSFETs to deliver up to 1.5A of output current. The device operates with an input voltage range from 4.5V to 40V and supports adjustable output voltages. It utilizes pulse width modulation (PWM) control for efficient regulation. The component is housed in an 8-pin SOIC package and is designed for applications requiring compact, high-efficiency DC-DC conversion solutions.
Feature Summary
- Integrates synchronous rectification with internal high-side and low-side power MOSFETs
- Supports wide input voltage range suitable for various bus architectures
- Utilizes fixed-frequency PWM control mode for stable operation
Applications
- Point-of-load regulation for industrial equipment
- Power supply stages for embedded computing systems
- Voltage regulation for communication infrastructure modules
Procurement Notes
Verify the specific suffix 'EDR8G' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering information matches the exact package variant required for your PCB layout. Cross-reference RoHS compliance status with the latest product change notices provided by onsemi before finalizing procurement.
Selection Notes
Select this component when a synchronous buck topology is required for higher efficiency compared to asynchronous designs. Consider the 1.5A current capability and 40V maximum input rating against system load requirements. Evaluate thermal performance within the SOIC-8 package constraints for the intended ambient operating conditions.
Part Context
This part belongs to the CS5141x family of low-voltage buck regulators from onsemi. The family includes variants such as CS51411, CS51412, and CS51413, which share similar control architectures but may differ in specific features or packaging options. These components are designed to replace older generation discrete solutions in space-constrained designs.
Replacement Considerations
Consult onsemi documentation for direct replacements if this part is obsolete. Verify that alternative devices maintain compatible pinouts and electrical parameters to ensure seamless integration without redesigning the surrounding circuitry.
