The MAX16824AUE+ is a high voltage, three channel, linear high brightness LED driver in 16 pin TSSOP package. It operates over 6.5V to 28V input voltage range. This device provides three open-drain constant current sinking outputs that are rated to 36V and deliver up to 150mA of current to each string of high brightness LEDs (HB LEDs). The current at each output is programmable by means of an external current sense resistor. The MAX16824 has three PWM inputs that control duty cycle of output current which allows wide LED dimming range to be implemented. The PWM inputs also function as on/off control for each corresponding output. The on-board pass elements minimize the need for external components while at same time providing ±5% LED current accuracy. It is used in architectural and decorative lighting, indoor and outdoor LED, video displays, LCD displays and backlighting.
