uP1746 - 2A High-Efficiency Synchronous-Rectified Buck Converter

General Description

The uP1746 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.

Key Features

  • include internal softstart, chip enable, under voltage, over temperature and over current protections. The uP1746 is available in space-saving TSOT23-5L, TSOT23-6L, WDFN2x2-6L and WQFN3x3-16L packages with adjustable version of output voltages.

uP1746 1MHz, 2A High-Efficiency Synchronous-Rectified Buck Converter General Description The uP1746 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 uP1746 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 uP1746 is capable of delivering 2A 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 softstart, chip enable, under voltage, over temperature and over current protections.
