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 and 250mΩ
a voltage divider. Other features include internal soft-start, Current Mode PWM Operation
chip enable, under-voltage, over-temperature and over-
current protections. The uP1722 is available in space-saving
Fixed Frequency: 1.5MHz
WDFN2x2-6L and TSOT23-5L packages with fixed or 100% Maximum Duty Cycle for Lowest Dropout
adjustable output voltage options.
