MP3324 8-Channel White LED Drivers Monolithic Power Systems (MPS) MP3324 8-Channel White LED (WLED) Drivers operate from 4V to 16V input voltage (VIN) range. These drivers apply eight internal current sources in each LED string terminal. The LED current of each channel is set by an external current-setting resistor, where each channel has a 100mA maximum current. The MP3324 WLED drivers support up to ten ICs cascaded to drive an LED array. These drivers employ separated Pulse Width Modulation (PWM) dimming and analog dimming for each LED channel.
