DESCRIPTION
The MP3204 is a step-up converter designed
for driving up to 5 series white LEDs from a
single cell Lithium Ion battery. The MP3204
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 MP3204 includes under-voltage lockout,
current limiting and thermal overload protection
preventing damage in the event of an output
overload. The MP3204 is available in a small
6-pin TSOT23 package.
