The SY2A39719 is a three-channel linear led driver integrated with low drop-out MOSFET. It is intended to deliver up to 0.15A output current on each channel. Three independent PWM dimming pins are available to achieve ON OFF dimming function for each channel. Measuring the voltage at input and output pin gives accurate open led protection and short led protection.
