MP3301
DESCRIPTION
The MP3301 is a step-up converter designed to drive WLEDS arrays from a single-cell, lithium-ion battery. The MP3301 uses a current-mode, fixedfrequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 200m V feedback voltage reduces power loss and improves efficiency. The MP3301 turns off in the presence of an open-circuit over-voltage condition.
The MP3301 includes under-voltage lockout, current limiting, and thermal-overload protection to prevent damage in the event of an output overload.
The MP3301 is available in a small 5-pin TSOT23 package.
