Product Overview
The RT8462GS is a high voltage/high 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 the maximum operating input voltage of 36V and output voltage up to 60V, the RT8462 is ideal for buck, boost or buck-boost operation. With the switching frequency programmable over 100kHz to 1MHz, the external inductor and capacitors can be small while maintaining high efficiency. Dimming can be done by either analogue or digital. The built-in clamping comparator and filter allow easy low noise analogue dimming conversion from digital signal with only one external capacitor.
