DC1784B

DC1784B is a LT3797EUKG triple LED boost controller demo board. DC1784B is a triple boost LED driver featuring the LT3797 triple boost LED controller. It accepts an input voltage from 2.5V to 40V (with higher transient) and drives three independent strings of up to 50V LEDs at 1A. DC1784B features independent PWM and analog dimming of each of the three LED strings. Each of the three channels has its own short-circuit protection, open LED protection and FAULT flag output. DC1784B features high efficiency at 310KHz switching frequency. At high LED string voltages up to 50V and 1A of LED current, the triple LED boost controller has 93.5% efficiency.
