Overview
The NCV891930MW01R2G is an automotive-grade synchronous step-down switching regulator manufactured by onsemi. It operates with an input voltage range of 4.5V to 36V and delivers a continuous output current of 3A. The device integrates a fixed 1V output configuration and supports a switching frequency of 2MHz. It features AEC-Q100 qualification for automotive reliability and operates within a junction temperature range of -40°C to 150°C. The component utilizes a compact MW50 package.
Feature Summary
- Synchronous buck topology for high efficiency
- Integrated power switches for compact design
- Automotive grade reliability certification
Applications
- Automotive infotainment systems
- Telematics control units
- Body control modules
Procurement Notes
Verify the specific suffix R2G corresponds to the required tape and reel packaging quantity. Confirm the fixed 1V output variant matches the system requirement, as other output voltages exist in the series. Ensure the MW50 package footprint aligns with the PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed 1V rail is required for automotive applications. The 3A output capability suits moderate load requirements. Consider the 2MHz switching frequency for smaller passive component sizes compared to lower frequency alternatives. Verify thermal management needs for the MW50 package under maximum load conditions.
Part Context
This part belongs to the NCV8919xx family of synchronous buck regulators designed for automotive environments. It shares architectural similarities with other members like the NCV891330 but differs in output voltage configuration and specific package options. The family targets robust power conversion in space-constrained automotive electronics.
Replacement Considerations
Check for direct pin-compatible substitutes within the same family offering different fixed output voltages if the 1V specification is flexible. Verify equivalent AEC-Q100 qualified parts from other manufacturers if supply constraints arise.
