The MAX1947ETA25+ is a compact, high-efficiency step-up DC-DC converter from Analog Devices / Maxim Integrated. It regulates output voltages up to 3.3V, making it suitable for powering µP/DSP cores, memory, and I/O rails in 1- and 2-cell battery-powered systems. This converter features an internal 800mA switch and synchronous rectifier, achieving up to 94% efficiency and eliminating the need for an external Schottky diode.
With high-frequency switching up to 2MHz, the MAX1947ETA25+ allows for small external components and low output ripple. It offers automatic pulse skipping at light loads, reducing supply current to 70µA for extended battery life. Maxim’s proprietary True Shutdown™ reduces supply current to just 2µA and fully discharges the output to ground. A 75ms RESET output flag provides power-on reset (POR) and undervoltage detection.
The MAX1947ETA25+ is available in a space-saving 8-pin TDFN package, suitable for surface mount applications. Its low input voltage capability of 0.7V and fixed output voltages make it ideal for portable electronics such as MP3 players, PDAs, digital still cameras, and cordless phones.
