    • AEC-Q100 Qualified with the Following Results:
    • Device Temperature Grade1: –40°Cto125°C Ambient Operating Temperature Range

    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.

    The SY2A39719HFA is a 3-channel linear led driver that delivery up to 0.15A output current per channel. It integrates three 1Ω PMOS, which allows low drop-out voltage. Three independent PWM dimming pins are available to achieve ON OFF dimming function for per channel. Monitor the input voltage and output voltage to implement open led protection and short led protection.
