High Efficiency, 40V Step-Up White LED Driver

The WD3119 is a constant current, high efficiency LED driver. Internal MOSFET can drive up to 10 white LEDs in series and 3S9P LEDs with 1.2A current limit and 40V OVP. A Pulse-Width-Modulation (PWM) signal can be applied to the EN pin for LED dimming. The device operates with 1MHz fixed switching f
