RT8492 - High Voltage 4-CH LED Driver Controller

The RT8492 is a 4-CH LED driver controller that delivers well matched LED current to each channel of LED string. With external current sources, the number of LEDs per string is only limited by the current source and the VIN/ VOUT conditions. The current mode PWM boost type controller operates at a p.
