The MP3301GJ-LF-Z is a step-up converter designed to drive WLEDS arrays from a single-cell, lithium-ion battery. The MP3301GJ-LF-Z uses a current-mode, fixed-frequency 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 MP3301GJ-LF-Z turns off in the presence of an open-circuit over-voltage condition. The MP3301GJ-LF-Z includes under-voltage lockout, current limiting, and thermal-overload protection to prevent damage in the event of an output overload. The MP3301GJ-LF-Z is available in a small 5-pin TSOT23 package.
