Fixed Frequency White LED Driver

The MP1518 is a Step-up converter designed for driving up to 6 series white LEDs from a single cell Lithium Ion battery. The MP1518 uses current mode, fixed frequency architecture to regulate the LED current, which is measured through an external Current Sense resistor. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The MP1518 includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload. The MP1518 is available in small 6-pin TSOT23 or 8-pin QFN (2mm x 2mm) packages. Also available is the MP1518DJE ideal for applications where low EMI is critical.
