WD3131 High Efficiency, 26V Step-Up White LED Driver WD3131 Http//:www.sh-willsemi.com Descriptions The WD3131 is a constant current, high efficiency LED driver. Internal MOSFET can drive up to 6 white LEDs in series and 3S13P LEDs with Min. 1.5A current limit and 26V OVP. A Pulse-Width-Modulation (PWM) signal can be applied to the EN pin for LED dimming. The device operates with 1MHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows use small external components. The WD3131 is available in SOT-23-6L package. Standard product is Pb-free and Halogen-free. SOT-23-6L Features  Input voltage range : 3~5.5V  Open LED Protection : 26V  Reference Voltage : 200mV (±5%)  Switching frequency : 1MHz (Typ.
