Description

The FAN5336 is a high-efficiency, low-noise, fixed-frequency PWM, current-mode, DC-DC boost regulator. It is designed for small LCD bias supply and white LED backlight supply applications. Depending on the application, a FAN5336 regulator can output up to 33V at up to 50mA output current. With output voltage up to 21V, the output current can be up to 100mA. FAN5336 can be used for power conversion as low as 9V output voltage.
