uP1728 - High-Efficiency Synchronous-Rectified Buck Converter

Key Features

  • The uP1728 is a high efficiency synchronous-rectified buck † 2.6V to 5.5V Input Voltage Range converter with internal power switches. Fixed 1.2MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency † † Adjustable Output from 0.6V to VIN Guaranteed 3.0A Output Current and small package, the uP1728 is ideally suitable for † Accurate Reference: 0.6V (+1%) portable devices and USB/PCIE-based interface cards, † Up to 95% Conversion.
