uP1722P/Q
1.5MHz, 1.3A, High-Efficiency
Synchronous-Rectified Buck Converter
General Description
Features
The uP1722 is a high efficiency synchronous-rectified buck 2.6V to 5.5V Input
Voltage Range
converter with internal power switches. Fixed 1.5MHz PWM 1.3A Peak Output Current operation allows possible smallest output ripple and external component size. With high conversion efficiency Accurate Reference with +/- 2% Accuracy
and small package, the uP1722 is ideally suitable for
0.6V (uP1722P)
portable devices and USB/PCIE-based interface cards
0.5V (uP1722Q)
where PCB area is especially concerned.
Up to 95% Conversion Efficiency
With internal low RDS(ON) switches, the uP1722 is capable of delivering 1.3A peak output current over a wide input
Typical Quiescent Current: 60uA
voltage range from 2.6V to 5.5V. The output
voltage is Integrated Low RDS(ON) Upper and Lower
MOSFET
adjustable from 0.6V/0.5V (uP1722P/uP1722Q) to VIN by
Switches: 300mΩ a...
