Overview
The NCV3066PG is a switching constant current regulator designed for high-brightness LEDs, manufactured by onsemi. It operates in Buck, Boost, and Inverting topologies with an internal switch rated for 1.5 A output current. The device supports analog and PWM dimming control and functions within an input voltage range of 3 V to 40 V. It is housed in an 8-pin PDIP package and is qualified to AEC-Q100 standards for automotive applications, operating at temperatures up to +125°C junction temperature.
Feature Summary
- Integrated 1.5 A internal power switch for direct LED driving
- Supports Buck, Boost, and Inverting converter topologies
- Enables precise LED brightness control via analog or PWM dimming signals
Applications
- Automotive exterior lighting systems
- High-brightness LED illumination modules
- Industrial LED driver circuits
Procurement Notes
Verify the package type matches design requirements; the PG suffix indicates a PDIP-8 through-hole package, distinct from surface-mount variants like DR2G. Confirm AEC-Q100 qualification is necessary for the specific automotive application. Check datasheet revisions for any recent mold compound updates or pinout changes before finalizing the bill of materials.
Selection Notes
Select this component when a robust, through-hole solution is required for automotive-grade LED regulation. The NCV prefix denotes automotive qualification, ensuring reliability under harsh thermal conditions. Compare against NCP3066 series if industrial grade suffices, but prioritize NCV3066PG for applications demanding extended temperature ranges and automotive certification.
Part Context
This part belongs to the NCP3066 family of switching regulators optimized for LED applications. The NCV3066 variant specifically meets automotive quality standards. It complements other onsemi PMIC solutions by providing a simple, single-inductor topology for constant current regulation without requiring external MOSFETs.
Replacement Considerations
NCP3066PG serves as the commercial-grade equivalent. Surface-mount alternatives include NCV3066DR2G and NCV3066OSTR. Verify package compatibility and thermal performance when substituting between through-hole and SMD versions.
