High Efficiency White LED Driver

The PT4110 is a high efficiency Step-up DC/DC converter designed for driving multiple strings of up to nine series-connected white LED from a single cell Lithium Ion battery. It regulates the output current, ideal for driving light emitting Diodes (LED) whose light intensity is proportional to the current passing through them. The external ballast resistor sets the LED current ranging from 5mA to 20mA, which CAN be easily adjusted using either a DC voltage or a pulse width modulated (PWM) signal alternatively. Its low 300mV feedback voltage reduces power loss and improves efficiency. By China Resources Powtech (Shanghai) Co., Ltd
