The RT8482 is a current mode PWM controller designed to drive an external MOSFET for high current LED applications. With a current sense amplifier threshold of 190mV, the LED current is programmable with one external current sense resistor. With a maximum operating input voltage of 36V and output voltage up to 48V, the RT8482 is ideal for buck, boost or buck-boost operation.


With 350kHz operating frequency, the external inductor and capacitors can be small while maintaining high efficiency.


Dimming can be either analog or PWM digital. The unique built-in clamping comparator and filter allow easy low noise analog dimming conversion from PWM signal with only one external capacitor.


The RT8482 is available in WQFN-16L 3x3 and SOP-16 packages.General Industrial High Power LED LightingDesk Lights and Room LightingBuilding and Street LightingIndustrial Display Backlight
