MXHV9910 LED Driver

Clare and Digi-Key introduce a low-cost, high-brightness (HB) LED driver

The MXHV9910 is a low-cost, high-brightness (HB) LED driver manufactured using Clare's high-voltage BCDMOS on SOI process. This driver has internal circuitry that allows it to operate from a universal AC line or from 8VDC to 450VDC. This highly versatile input operating voltage enables this IC to be used in a broad range of HB LED applications.

Overview

This driver features a fixed-frequency, peak-current control method, which provides an ideal solution for driving multiple LEDs in series and in parallel. Additionally, LED dimming can be implemented by applying a small DC voltage to the LD pin or a low-frequency digital PWM signal to the PWMD pin.

The MXHV9910 is available in a standard 8-lead SOIC package and a thermally enhanced 8-lead SOIC package with an Exposed Thermal Pad (EP)
