RT8477
High
Voltage High Current LED Driver
General Description
The RT8477 is a current mode PWM controller designed to drive an external
MOSFET for high current LED applications with wide input
voltage (4.
5V to 50V) and output
voltage (up to 50V) ranges.
With internal 380kHz 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.
LED Dimming control can be done by analog.
The RT8477 is now available in the SOP-8 package.
