RT8485 Overview
The RT8485 is a current-mode PWM controller designed to drive an external MOSFET for high current LED applications. With a current sense amplifier threshold of 315mV, the LED current is adjustable with one external current sense resistor. With the maximum operating input voltage of 36V and output voltage up to 150V, the RT8485 is ideal for Buck, Boost or Buck-Boost operation.
