uP1728

uP1728 1.2MHz, 3.0A, High-Efficiency Synchronous-Rectified Buck Converter General Description 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 Efficiency where PCB area is especially concerned. † Low Quiescent Current With internal low RDS(ON) switches, the uP1728 is capable of delivering 3.0A output current over a wide input voltage † Integrated Low RDS(ON) Upper and Lower MOSFET Switches: 80mΩ and 60mΩ range from 2.6V to 5.5V. The output voltage is adjustable from 0.6V to VIN by a voltage divider. † Current Mod...
