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. A current-mode control loop has a fast transient response that provides excellent load regulation within of output voltage. The FAN5336 switches at fixed 1.5MHz frequency, allowing the use of small, low-cost external components. Constant frequency switching results in low input noise and small output capacitors. FAN5336 provides cycle-by-cycle current limiting up to 1.5A peak current. The FAN5336 may be used to drive a serial flash LED with up to 100mA current at 21V for a maximum of 400ms on-time and 10% duty cycle.
