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 200mV 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.
