WD3132 High Efficiency, 38V Step-Up White LED Driver for Medium LCD Panel Backlight WD3132 Http//:www.sh-willsemi.com Descriptions The WD3132 is a constant current, high efficiency LED driver. Internal MOSFET can drive up to 10 white LEDs in series and 10S4P / 8S5P LEDs with 38V OVP. Peak inductor current limit is larger than 1.5A. For LED dimming, a Pulse-Width-Modulation (PWM) signal can be applied to the EN pin. The device operates at optimized 600k Hz fixed switching frequency to reduce ou.

WD3132 High Efficiency, 38V Step-Up White LED Driver for Medium LCD Panel Backlight WD3132 Http//:www.sh-willsemi.com Descriptions The WD3132 is a constant current, high efficiency LED driver. Internal MOSFET can drive up to 10 white LEDs in series and 10S4P / 8S5P LEDs with 38V OVP. Peak inductor current limit is larger than 1.5A. For LED dimming, a Pulse-Width-Modulation (PWM) signal can be applied to the EN pin. The device operates at optimized 600k Hz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows use small external components. The WD3132 is available in SOT-23-6L package. Standard product is Pb-free and Halogen-free. Features  Input voltage range : 3~5.5V  Open LED Protection : 38V  Reference Voltage : 200mV (±5%)  Switching frequency : 600k Hz (Typ.)  Efficiency : Up to 92% (10S4P)  Main switch current limit : 1.5A (Min.)  PWM Dimming frequency : 5KHz to 200KHz  PWM Dimming Duty : Min. 4% App.
