PT4101 is a driven by a single lithium battery up to 6 series LED boost converter , the 5V input, can drive 8 " 10 LED. PT4101 includes a power MOS transistor, fixed frequency current mode to regulate the LED current and, through an external current monitoring resistor to measure this current. their low 104mV feedback voltage reduces power consumption and increase efficiency . OV pin monitors the output voltage and the output as a result of entering an open state overvoltage shutdown converter ; contains undervoltage lockout , current limit and thermal protection , in order to avoid output overload damage to the device .
