Overview
The CS51414GD8G is a synchronous buck switching regulator IC manufactured by onsemi. It operates with an input voltage range of 4.5V to 40V and provides a single adjustable output from 1.27V to 38V at up to 1.5A. The device features a fixed 520kHz switching frequency and functions in a standard non-inverting buck topology. It is housed in an 8-SOIC package (0.154 inch width) and supports junction temperatures from -40°C to 150°C.
Feature Summary
- Synchronous rectification architecture for improved efficiency
- Integrated high-side and low-side power switches
- Fixed internal switching frequency simplifies external component selection
Applications
- Point-of-load regulation for industrial equipment
- Power supply stages for embedded computing systems
- Battery-powered devices requiring efficient step-down conversion
Procurement Notes
Verify the exact part number suffix, as 'CS51414GD8G' differs from the documented 'CS51414GDR8G'. Confirm RoHS compliance and lead-free status via the official datasheet. Check current manufacturing status, as related variants may be obsolete or discontinued.
Selection Notes
Select this component when a compact synchronous buck solution is required for inputs up to 40V. Ensure the load current does not exceed 1.5A and that the thermal design accommodates the SOIC-8 package limitations. Verify that the required output voltage falls within the 1.27V to 38V adjustable range.
Part Context
This device belongs to the CS5141x family of synchronous buck regulators from onsemi. These parts are designed for applications demanding high efficiency and minimal external component count. The family typically shares similar control architectures but varies in current ratings, packaging, or specific feature sets like enable pins or tracking capabilities.
Replacement Considerations
The CS51414EDR8G is listed as a parameter-equivalent substitute. Verify pinout compatibility and electrical specifications against the original requirement before substitution.
