NCV3065DR2G

Overview

The NCV3065DR2G is a monolithic switching regulator designed for high brightness LED applications. It operates as a synchronous buck, boost, or inverting converter with an internal switch capable of delivering up to 1.5 A output current. The device supports an input voltage range from 3 V to 40 V and features a fixed switching frequency of 250 kHz. It provides constant current regulation for driving series LED strings. The component is housed in an 8-pin SOIC package and is qualified under the AEC-Q100 standard for automotive use.

Feature Summary

• Integrated synchronous rectification for improved efficiency
• Constant current control for stable LED brightness
• Supports multiple topologies including buck, boost, and inverting configurations

Applications

• High brightness LED lighting systems
• Automotive exterior and interior illumination
• Low voltage DC powered landscape lighting

Procurement Notes

Verify the specific suffix DR2G corresponds to the tape and reel packaging format required for your assembly line. Confirm that the NCV prefix meets your organization's automotive quality standards and AEC-Q100 compliance requirements. Ensure the operating temperature range aligns with your system's thermal design constraints before finalizing procurement.

Selection Notes

Select this component when a single-chip solution is needed for driving LEDs with currents up to 1.5 A. It is suitable for designs requiring flexible topology options such as step-up or step-down conversion from a wide input voltage range. Consider its integrated synchronous nature for applications prioritizing power efficiency over external gate drive complexity.

Part Context

This part belongs to the NCP3065 family of LED drivers manufactured by onsemi. The NCV variant specifically denotes automotive-grade qualification. It serves as a dedicated power management IC for replacing discrete solutions in compact LED driver circuits, offering integrated protection features and simplified external component counts.

Replacement Considerations

The NCP3065DR2G is the commercial grade equivalent. Verify pinout compatibility if substituting with other members of the NCP3065 series.
