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. The uP1746 is available in space-saving
TSOT23-5L, TSOT23-6L, WDFN2x2-6L and WQFN3x3-16L
packages with adjustable version of output voltages. uP1746PMT5-00
