Overview

The RT8452 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 the maximum operating input voltage of 36V and output voltage up to 48V, the RT8452 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 done by either analog or digital. A built-in clamping comparator and filter allow easy low noise analog dimming conversion from digital signal with only one external capacitor. An unique True PWM dimming control is made easy with MOSFET under LED string. A very high dimming ratio can be achieved by adopting both analog/ digital dimming and True PWM dimming together. The RT8452 is available in WQFN-16L 3x3 and SOP-16 packages.
