The ROHM single channel LED controller has high side current detection amplifier is built-in. PWM dimming duty can be freely set with built-in PWM generation circuit. PWM dimming realizes by driving an external P-ch MOSFET. Two systems of analogue dimming are built-in. High precision 3.0 V output power supply for analogue dimming and PWM dimming setting is built-in. AEC-Q100 qualified
