ONNCP3065
Overview
The NCP3065 is a monolithic switching regulator specifically designed for high-brightness LED applications. It operates with a wide input range of 3V to 40V and includes an internal 1.5A switch, allowing for various power topologies such as buck, boost, and buck-boost (SEPIC).
Why Choose This Part
This regulator offers high-frequency operation at 150kHz and includes built-in open LED and output short-circuit protection. It supports both PWM and analog dimming, providing engineers with flexible control over LED brightness while minimizing component count with its internal switch.
Applications
Key Specifications
Getting Started
Engineers can evaluate the design using the NCP3065D3SLDGEVB evaluation board, which demonstrates a SEPIC topology for 700mA current regulation. Designers should focus on inductor selection and feedback resistor values to set the target constant current output based on the 235mV internal reference voltage.
