General Description
The EV0056 evaluation board is designed for
backlights using white LEDs. It implements
MPS’ MP1518 fixed frequency step-up
converter.
The MP1518 is a 6 pin thin SOT23 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. It’s low 100mV
feedback voltage reduces power loss and
improves efficiency. To prevent damage due
to an open circuit condition, the OV pin
monitors the output voltage and turns off the
converter if an over-voltage condition is
present.
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 a small 6
lead TSOT23 package.
