LED Driver ICs Deliver High Voltage

Tue, 01/08/2008 - 5:29am

LED Driver ICs Deliver High VoltageSupertex, Inc. introduced its models CL320, CL325 and CL330 LED driver ICs, each consisting of three channels of constant current output, designed to drive three LED strings at currents of 20 mA, 25 mA and 30 mA each, respectively. Each part comes in an 8-lead SOIC (with heat slug) package. The only external component required is a single ceramic bypass capacitor, making the PCB designs simple, and the same capacitor can be shared with several drivers. Separate enable pins for each channel allow pulse width modulated (PWM) dimming, three-step linear dimming or individual disconnection of any faulty LED string. They are designed for applications in LED backlighting LCD panels, indicator lamps, decorative lights and for general lighting.
