Synchronous-Rectified Buck Converter
General Description
Features
The uP1728 is a high efficiency synchronous-rectified buck 2.6V to 5.5V Input Voltage Range
converter with internal power switches. Fixed 1.2MHz PWM operation allows possible smallest output ripple and external component size. With high conversion efficiency
Adjustable Output from 0.6V to VIN Guaranteed 3.0A Output Current
and small package, the uP1728 is ideally suitable for Accurate Reference: 0.6V (+1%)
portable devices and USB/PCIE-based interface cards, Up to 95% Conversion Efficiency
where PCB area is especially concerned.
Low Quiescent Current
With internal low RDS(ON) switches, the uP1728 is capable of delivering 3.0A output current over a wide input voltage
Integrated Low RDS(ON) Upper and Lower MOSFET Switches: 80mΩ and 60mΩ
range from 2.6V to 5.5V. The output voltage is adjustable from 0.6V to VIN by a voltage divider.
