RT8480 Overview
The RT8480 is a current mode PWM controller designed to drive an external MOSFET for high current LED applications. With a low side current sense amplifier threshold of 190mV, the LED current is programmable with one external current sense resistor. With programmable operating frequency up to 800kHz, the external inductor and capacitors can be small while maintaining high frequency.
