DESCRIPTION
The EV3302DG-00A is an evaluation board for the
MP3302DG, a step-up converter designed for
driving up to 27 white LEDs from a single cell lithium
Ion battery. The EV board is optimized for the load
of 3 white LEDs in series, 9 strings panel.
The MP3302 uses current mode, fixed frequency
architecture to regulate the LED current, which is
measured through an external current sense
resistor. Its low 208mV feedback voltage reduces
power loss and improves efficiency. The MP3302
monitors the output voltage and turns off the
converter if an over-voltage condition is present
due to an open circuit condition.
The MP3302 includes under-voltage lockout,
current limiting and thermal overload protection
preventing damage in the event of an output
overload.
The MP3302 is available in small 8-pin QFN
(2mm x 3mm) package.
