Overview
The NCV8852DR2G is an automotive-grade, non-synchronous buck switching regulator controller manufactured by onsemi. It operates within a wide input voltage range and supports a switching frequency between 100 kHz and 500 kHz. The device delivers a maximum output current of 230 mA with a fixed output voltage of 8 V. It features a duty cycle capability up to 100% and functions reliably across an extended temperature range from -40°C to +150°C. Packaged in an SOIC-8 surface-mount format, it meets AEC-Q100 qualification standards for automotive applications.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Non-synchronous buck topology with 100% maximum duty cycle
- Wide operating junction temperature range up to 150°C
- Fixed 8 V output voltage configuration
Applications
- Automotive power distribution systems
- Battery-powered electronic modules
- General DC-DC conversion in vehicle networks
Procurement Notes
Verify the specific suffix DR2G against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the application design accounts for the non-synchronous nature of the controller and the fixed 8 V output constraint. Confirm thermal management requirements for the SOIC-8 package under maximum load conditions at elevated ambient temperatures.
Selection Notes
Select this component when an automotive-qualified, non-synchronous buck solution is required with a fixed 8 V output. It is suitable for designs needing a simple control loop without external synchronous rectifier drivers. Consider the 230 mA output limit and the 100 kHz to 500 kHz frequency range for inductor selection. Verify compatibility with the system's input voltage profile and thermal constraints.
Part Context
This part belongs to the NCV8852 series of automotive power management ICs. It is specifically designed as a non-synchronous buck controller, distinguishing it from synchronous variants like the NCV8851. The series targets robust performance in harsh automotive environments, offering high temperature tolerance and compliance with automotive quality standards.
Replacement Considerations
Direct substitutes include other NCV8852 variants such as NCV885201D1R2G, provided the output voltage and pinout configurations match. Non-automotive equivalents like the standard MC33063 may require significant circuit redesign due to differences in control architecture and temperature ratings.
