The AME5172 is a high-efficiency, current mode, synchronous PWM Boost DC-DC Converter with fixed 3.3V output voltage for system applications powered by single or double cell NiMH or Alkaline battery pack. Built-in 0.35 NMOS switch and 0.45 PMOS synchronous rectification significantly improves efficiency and reduces external components count. High switching frequency (at 1.2MHz) allows easy filtering and faster loop performance.
