Microchip Technology CL320, CL325, & CL330 LED Drivers

Microchip Technology CL320, CL325, and CL330 LED Drivers are linear, 3-channel devices designed to drive three strings of LEDs at a constant current of 20mA, 25mA or 30mA, respectively. These 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 LED Drivers provide over-temperature protection, 90V standoff voltage, and a fixed drive current with a ±6% tolerance over a Vout range of 4V to 15V. The CL320, CL325, and CL330 LED Drivers are ideal for applications in low cost LED backlighting, LCD panels, indicator lamps, decorative lights, and general lighting.
