uP1704AB-DS-P0000uP1704A/B1.5MHz, 600mA, High-Efficiency Synchronous-Rectified Buck ConverterGeneral DescriptionThe uP1704A/B is a high efficiency synchronous-rectified buck converter with internal power switches. Fixed 1.5MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1704A/B is ideally suitable for portable devices and USB/PCIE-based interface cards where PCB area is especially concerned. With internal low RDS(ON) switches, the uP1704A/B is capable of delivering 600mA output current over a wide input voltage range from 2.6V to 5.5V. The output voltage is adjustable from 0.6V/0.5V (uP1704A/uP1704B) to VIN by a voltage divider. Other features include internal soft-start, chip enable, under-voltage, over-tempe……
