FAN5336UMPX

FAN5336 1.5MHz TinyBoost™ Regulator with 33V Integrated FET Switch Features Description ■ 1.5MHz Switching Frequency 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. ■ Low Noise ■ Adjustable Output Voltage ■ Up to 1.5A Peak Switch Current ■ Low Shutdown Current: 3.6s 100 Switch On-Resistance VIN = 3.6V 0.4 Quiescent Current OFF Mode Current No Switching, VFB ≥ 1.27V 0.7 Switching 6.5 VSHDN = 0V 0.1 Device ON Shutdown Threshold mA mA 3.0 µA 1.5 Device OFF V 0.5 Shutdown Pin Bias Current VSHDN = 0V or VSHDN = 5.5V Feedback Voltage (VREF) ILoad = 0mA, VIN = 3.6V at 25°C 1.205 Feedback Pin Bias Current Feedback Voltage Line Regulation(3) Ω 3.0V < VIN < 5.5V, ILOAD = 0mA 1 10 nA 1.230 1.255 V 1 10 nA 0.4 1.5 %/V 1.85 MHz Switching Frequency 1.15 1.50 Maximum Duty Cycle 87 93 Start-up Turn-on Time VIN = 3.0V, IOUT = 75mA 3.0 Load Regulation VIN = 3.6V, 1mA < ILoad
