uP1713
1MHz, 2.0A, High-Efficiency
Synchronous-Rectified Buck Converter
General Description
Features
The uP1713 is a high efficiency synchronous-rectified buck converter with internal power switches. Fixed 1MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency and small package, the uP1713 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 uP1713 is capable of delivering 2.0A output current over a wide input
voltage range from 2.6V to 5.5V. The output
voltage is adjustable from 0.6V to V by a
voltage divider. Other features include
IN
internal soft-start, chip enable, over-
voltage, under
voltage, over-temperature and over-current protections. The uP1713 is available in a space-saving WQFN3x316L, WLCSP1.5x1.5-9B or PSOP-8L packages.
