uP1722P/Q

1.5MHz, 1.3A, High-Efficiency

Synchronous-Rectified Buck Converter

Features

General Description

The uP1722 is a high efficiency synchronous-rectified buck

converter with internal power switches. Fixed 1.5MHz PWM

operation allows possible smallest output ripple and

external component size. With high conversion efficiency

and small package, the uP1722 is ideally suitable for

portable devices and USB/PCIE-based interface cards

where PCB area is especially concerned.

2.6V to 5.5V Input Voltage Range

1.3A Peak Output Current

Accurate Reference with +/- 2% Accuracy

0.6V (uP1722P)

0.5V (uP1722Q)

Up to 95% Conversion Efficiency

Typical Quiescent Current: 60uA

With internal low R_DS(ON)switches, the uP1722 is capable

of delivering 1.3A peak output current over a wide input

voltage range from 2.6V to 5.5V. The output voltage is

adjustable from 0.6V/0.5V (uP1722P/uP1722Q) to V_INby

a voltage divider. Other features include internal soft-start,

chip enable, under-voltage, over-temperature and over-

current protections. The uP1722 is available in space-saving

WDFN2x2-6L, TSOT23-5L and SOT23-5L packages with

fixed or adjustable output voltage options.
