WD3131 Datasheet (WillSEMI) - 26V Step-Up White LED Driver

WD3131, 26V Step-Up White LED Driver

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 switc
