High Voltage Multi-Topology LED Driver
The RT8463 is a current mode PWM regulator for LED driving applications. With a ,2A power switch, wide input voltage (4.5V to 50V) and output voltage (up to ,50V) ranges, the RT8463 can operate in any of the three common topologies : ,Buck, Boost or Buck-Boost.With 470kHz operating frequency, the size of the ,external PWM inductor and input/output capacitors can be minimized. High ,efficiency is achieved by a 100mV current sensing control.,,Brightness dimming can be controlled from either analog or PWM signal. A ,unique built-in clamping comparator and filtering resistor allow easy low noise ,analog dimming conversion from PWM signal with only one external capacitor.,,The RT8463 is available in the TSSOP-14 (Exposed pad) and WDFN-12L 3x3 ,packages.,,
