Overview
The NCV3011DTBR2G is a single-output step-down DC-DC controller IC from onsemi, designed for automotive applications. It supports Buck and Boost topologies with a switching frequency of 400 kHz. The device operates within an input voltage range of 4.7 V to 28 V and provides a regulated output of 3.3 V at up to 8 A. It features a 0.8 V ±1.0% reference voltage and achieves a maximum duty cycle of 83%. The component functions reliably across a temperature range of -40°C to +140°C and is housed in a 14-pin TSSOP package.
Feature Summary
- Supports Buck and Boost converter topologies for flexible power conversion designs
- Integrated 0.8 V reference voltage ensures precise output regulation accuracy
- Automotive-grade qualification ensures reliability under harsh environmental conditions
Applications
- Automotive infotainment systems
- Vehicle lighting control modules
- Industrial sensor power supplies
Procurement Notes
Verify the specific suffix 'DTBR2G' matches the required tape-and-reel packaging format. Confirm that the automotive grade designation aligns with your system's environmental requirements. Check for end-of-life status as some sources indicate potential obsolescence. Ensure compatibility with your PCB footprint for the 14-TSSOP package before finalizing orders.
Selection Notes
Select this component when a robust, automotive-rated buck controller is required for high-current applications. The fixed 400 kHz frequency simplifies external component selection compared to adjustable variants. Consider the 8 A output capability and wide input voltage range for versatile integration into vehicle electrical architectures requiring stable 3.3 V rails.
Part Context
This part belongs to onsemi's NCV series, which denotes automotive-grade components meeting strict quality standards. It is functionally related to the NCP3011 but distinguished by its enhanced reliability specifications for automotive use. The device serves as a core control element in switching power supplies, replacing older linear regulators or less robust controllers in modern vehicle electronics.
Replacement Considerations
The NCP3011DTBR2G is a non-automotive variant with similar electrical characteristics but lacks automotive qualification. Verify if the standard grade meets your application's thermal and vibration requirements. No direct pin-compatible automotive substitutes are confirmed in public documentation; consult onsemi for current alternative recommendations.
