MP3221 2.7A, 1.2MHz, High-Efficiency Step-Up Converter With Input Disconnect DESCRIPTION FEATURES The MP3221 is a 1.2MHz frequency, 6-pin Integrated 88m Power MOSFET TSOT23 current mode step up converter 270A Quiescent Current intended for small, low power applications. The 2.5V to 6V Input Voltage device can step up three-cell alkaline, NiCd, 3V to 6V Output Voltage and NiMH batteries, or a single-cell Li-on 1.2MHz Fixed Switching Frequency battery up to 6V. It is capable of delivering 1A Internal 2.7A Switch Current Limit output current at 5V with a supply voltage of 3V. Integrated Input Disconnect Driver The MP3221 provides the internal soft start and Internal Soft Start and Compensation compensation to minimize the external True Output Disconnect from Input component count and help producing a Under Voltage Lockout compact solution. It integrates a FAULT driver Short-Circuit Protection for external PMOS to disconnect the output Over-Temperature Protection from input when the part shuts down or in Available in a 6-Pin TSOT23-6 Package output short circuit condition. This disconnect feature allows the output to be completely APPLICATIONS discharged, thus allowing the part to draw less Single-Cell Lion Battery or Three-Cell than 1A off current in shutdown mode. Alkaline, NiCd, or NiMH Battery Based Products The MP3221 is available in a small 6pin Portable Media Players TSOT23 package.
