Overview
The NCV3065PG is an automotive-grade switching voltage regulator from onsemi, designed for high-brightness LED applications. It supports Buck, Boost, and Inverting topologies with a maximum input voltage of 40 V and a constant output current capability of 1.5 A. Operating within a temperature range of -40 °C to +125 °C, it features a fixed switching frequency of 250 kHz. The device is housed in an 8-pin DIP package and holds AEC-Q100 qualification.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- Integrated synchronous buck regulator topology
- Constant current drive capability for HB-LEDs
Applications
- High-brightness LED lighting systems
- Automotive exterior lighting modules
- Low-voltage DC power supply conversion
Procurement Notes
Verify the specific suffix 'PG' corresponds to the 8-pin DIP package configuration when sourcing. Confirm that the automotive grade designation aligns with project requirements for extended temperature operation. Ensure compatibility with existing PCB footprints if replacing surface-mount variants. Cross-reference datasheet revisions to confirm pinout consistency across manufacturing batches.
Selection Notes
Select this component for designs requiring through-hole mounting solutions for automotive LED drivers. The 40 V input limit suits low-voltage DC sources common in vehicle architectures. Consider thermal management needs due to the 1.5 A output capacity in a DIP enclosure. Evaluate board space constraints as the DIP footprint differs significantly from SOIC or DFN alternatives.
Part Context
This part belongs to the NCP3065/NCV3065 family of switching regulators optimized for LED driving. While other variants like NCV3065DR2G offer surface-mount packaging, the PG suffix denotes the dual-in-line package version. The series provides flexible topology options including step-up, step-down, and inversion modes for diverse power conversion tasks.
Replacement Considerations
NCP3065PG serves as the commercial equivalent. Surface-mount alternatives include NCV3065DR2G (SOIC-8) and NCP3065MNTXG (DFN-8). Verify package dimensions and thermal characteristics when substituting between through-hole and surface-mount technologies.
