The uP1711 is a high-efficiency synchronous-rectified buck converter with internal power switches. User programmable up to 4MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1711 is ideally suitable for portable devices and USB/PCIEbased interface cards where PCB area is especially concerned.
With internal low RDS(ON) switches, the uP1711 is capable of delivering 2A output current over a wide input voltage ranging from 2.6V to 6.0V. The output voltage is adjustable from 0.8V to VIN by a voltage divider. Other features include internal soft-start, chip enable, over-voltage, undervoltage, over-temperature and over-current protections. The uP1711 is available in a space-saving MSOP-10L or VDFN3x3-10L package.
