NCP3065MNTXG

Overview

The NCP3065MNTXG is a monolithic switching regulator designed for high brightness LED applications. It delivers a constant output current of 1.5 A with an internal synchronous switch. The device supports Buck, Boost, and Inverting topologies, operating at a switching frequency of 250 kHz. It accepts input voltages up to 40 V and features a low feedback voltage of 235 mV nominal. The component operates within a temperature range of -40°C to +125°C TJ and is housed in an 8-DFN (4x4 mm) package.

Feature Summary

• Integrated synchronous buck regulator topology for efficient power conversion
• Configurable as step-down, step-up, or inverting converter with minimal external components
• Supports analog and PWM dimming control for LED brightness adjustment

Applications

• High brightness LED lighting systems
• MR16 and general illumination fixtures
• Battery-powered lighting applications using lead-acid batteries

Procurement Notes
