NW2L510

The NW2L510 is a driver specially designed for back-lighting. It consists of a high accuracy current sink that allows low duty dimming and a high efficiency step-up converter with an integrated low side and high side power MOSEFT. It runs with an optimal 0.6MHz frequency that enables use of small external components while still providing best efficiencies. It has an internal current limit as high as 1A, and it can drive up to 8 LEDs and 50mA in total output current. True PWM-Dimming can be achieved through the EN pin. One of the most important features of NW2L510 is that it provides an accurate current at dimming duty cycle down to 0.1%. This is very important for backlights that need to dim to very low light while still providing good consistency.

For maximum protection, the NW2L510 has an internal OVP protection at 30V to prevent the chip from damages when the LED string is not connected to the output.

NW2L510 is available in a space-saving DFN2x2-6 package and SOT23-6 package.
