RT8482应用电路(高电压高电流LED驱动器控制器)

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.
