GENERAL DESCRIPTION
The EV1518DG-00A is an evaluation board for
the MP1518, 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.
