Monolithic Power Systems, Inc. Voltage Regulators - DC DC Switching Regulators MP3115DT-LF-Z

The MP3115DT-LF-Z is a synchronous, fixed frequency, current mode step-up converter designed to boost a single AA alkaline battery to output voltages of 2.5V or 3.3V. It operates with an input voltage range of 0.95V to 2.5V and can deliver up to 200mA output current. The device features an integrated P-Channel synchronous rectifier, which enhances efficiency by eliminating the need for an external Schottky diode. Key features include inrush current limiting, output short circuit protection, and a shutdown mode that reduces current draw to less than 1¬µA. The MP3115DT-LF-Z operates at a switching frequency of 1.3MHz, allowing for smaller external components and a compact design suitable for various applications, including MP3 players, wireless mice, and audio recorders. It is housed in a 6-pin SOT23 package and is rated for operation within a temperature range of -40¬8C to +85¬8C.
