AWINIC AW9961
The AW9961 is a white LED driver with integrated boost converter. With an internal 40V switch FET, the AW9961 drives up a string of up to 10 LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components.| Part No. | AW9961 |

APPLICATIONS
● Mobile Phones● Portable Media Players
● GPS Receivers The default white LED current is set with the external sense resistor RSET, and the feedback voltage is regulated to 200mV, as shown in the typical application. During the operation, the LED current can be controlled by using the 1-wire digital interface through the CTRL pin. Alternately, a pulse width modulation (PWM) signal can be applied to the CTRL pin through which the duty cycle determines the feedback reference voltage.
