uP1722Q

uP1722P/Q 1.5MHz, 1.3A, High-Efficiency Synchronous-Rectified Buck Converter General Description Features The uP1722 is a high efficiency synchronous-rectified buck † 2.6V to 5.5V Input Voltage Range converter with internal power switches. Fixed 1.5MHz PWM † 1.3A Peak Output Current operation allows possible smallest output ripple and external component size. With high conversion efficiency † Accurate Reference with +/- 2% Accuracy and small package, the uP1722 is ideally suitable for „ 0.6V (uP1722P) portable devices and USB/PCIE-based interface cards „ 0.5V (uP1722Q) where PCB area is especially concerned. † Up to 95% Conversion Efficiency With internal low RDS(ON) switches, the uP1722 is capable of delivering 1.3A peak output current over a wide input † Typical Quiescent Current: 60uA voltage range from 2.6V to 5.5V. The output voltage is † Integrated Low RDS(ON) Upper and Lower MOSFET adjustable from 0.6V/0.5V (uP1722P/uP1722Q) to VIN by Switches: 300mΩ a...
