Overview
The NCP3065DR2G is a synchronous buck regulator from onsemi, packaged in an SOIC-8 surface-mount format. It operates with a fixed switching frequency of 250 kHz and supports a maximum input voltage of 40 V. The device delivers a constant output current of 1.5 A, suitable for high-brightness LED applications. It functions as a DC-DC converter with a Buck topology, offering an output voltage range between 3 V and 8 V. The component is designed for efficient power management within the NCP3065 series.
Feature Summary
- Integrated synchronous rectification for improved efficiency
- Fixed internal switching frequency simplifies external component selection
- Constant current regulation capability for driving LEDs
Applications
- High-brightness LED lighting systems
- General-purpose DC-DC conversion
- Battery-powered portable devices
Procurement Notes
Verify the specific suffix DR2G to confirm the SOIC-8 package and tape-and-reel packaging configuration. Ensure compatibility with the required input voltage range up to 40 V and the target load current of 1.5 A. Cross-reference the datasheet for thermal performance requirements under your specific operating conditions.
Selection Notes
Select this part when a compact synchronous buck solution is needed for LED drivers or general power supplies. Compare against the NCV3065DR2G if automotive qualification via AEC-Q100 is required, as the standard NCP variant may not hold this certification. Consider the DFN-8 option if lower profile packaging is preferred over the SOIC-8 form factor.
Part Context
This component belongs to the NCP3065 series of switching regulators. It shares functional similarities with other members like the NCP3066 but differs in specific control features and pin configurations. The series is designed for cost-effective, high-efficiency power conversion in space-constrained electronic designs.
Replacement Considerations
The NCV3065DR2G is a verified alternative within the same family, distinguished by its automotive-grade AEC-Q100 qualification. Other series members like the NCP3066 offer different control architectures and should be evaluated for pin-to-pin compatibility before substitution.
