RT8480 Datasheet (Richtek) - High Voltage Boost/SEPIC Controller

RT8480, High Voltage Boost/SEPIC Controller

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
