MP3208

Pinout




Description

The MP3208 is a 5-pin TSOT23 step-up converter designed for driving up to six (6) series white LEDs from a single-cell Lithium Ion battery. The MP3208 uses a current limited, variable frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 0.3V feedback threshold reduces power loss and improves efficiency. To prevent damage due to an open circuit condition, the BIAS pin can measure the output voltage and turn off the converter if an over-voltage condition is present.It includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MP3208 is available in a small 5pin TSOT23 package.
