This reference design uses the MAX16834 to build a 112.5W boost LED driver for driving long strings of LEDs. These long strings of LEDs are widely used in street lights and parking lot lighting.
Input voltage: 24VDC ±5% (1.49A)
V LED configuration: two strings in parallel, each string consists of 19 WLEDs, 5Ω resistor for current balance. The current per string is 750mA, providing 1.5A when driven at 75V.
Dimming: 50µs (minimum) on-pulse, 200:1 maximum dimming ratio, 100Hz dimming frequency.
