1W High Power White LED Driver PAM2801 Features n LED Power Efficiency: up to 90% n LED Current Accuracy: ± 3%(V IN=3.2V to 1.1 V @V F=3.4V) n Low Start-Up Voltage: 0.9V(I LED=243mA) n Low Hold Voltage:0.65V(I LED=95mA) n Internal 2A MOSFET Switch n 1.0MHz Switching Frequency n Uses Small,Low Profile External Components n Low R DS(ON): 100mΩ (TYP.) n Open LED Protection n Over Temperature Protection n Low Profile SOT-23 Package n Pb-Free Package General Descriptio n The PAM2801 is a step-up DC-DC converter that delivers a regulated output current. The device switches at a 1.0MHz constant frequency, allowing for the use of small value external inductor and ceramic capacitors. The PAM2801 is targeted to be used for driving 1W white LED from a 0.9V to 3.2V input.
