Supertex CL3xx LED Drivers
Supertex´s CL3xx family of LED drivers is designed to drive three strings of LEDs at a constant current of 20, 25 or 30mA. The devices contain separate enable pins for each channel to allow PWM dimming, three-step linear dimming, and individual disconnection of any faulty LED string. These drivers by Supertex provide over-temperature protection, 90V standoff voltage, and a fixed drive current with a ±6% tolerance over a Vout range of 4-15V. The product is ideal for applications in low cost LED backlighting, LCD panels, indicator lamps, decorative lights, and general lighting.
