uP1727Q
uPI Semiconductor
1.0MHz, 3.0A, High-Efficiency Synchronous-Rectified Buck Converter
Package Type: WDFN3x3-10L
The uP1727Q is a high efficiency synchronous-rectified buck converter with internal power switches. Fixed 1.0MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1727Q 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 uP1727Q is capable of delivering 3.0A output current over a wide input voltage range from 2.6V to 5.5V. The output voltage is adjustable from 0.6V to VIN by a voltage divider. Other features include internal soft-start, chip enable, overvoltage, under-voltage, over-temperature and over-current protections. The uP1727Q is available in a space-saving WDFN3x3-10L package.
