uP1728

1.2MHz, 3.0A, High-Efficiency

Synchronous-Rectified Buck Converter

Features

General Description

The uP1728 is a high efficiency synchronous-rectified buck

converter with internal power switches. Fixed 1.2MHz

PWM operation allows possible smallest output ripple and

external component size. With high conversion efficiency

and small package, the uP1728 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

Adjustable Output from 0.6V to V_IN

Guaranteed 3.0A Output Current

Accurate Reference: 0.6V ( 1%)

Up to 95% Conversion Efficiency

Low Quiescent Current

With internal low RDS(ON) switches, the uP1728 is capable

of delivering 3.0Aoutput 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.

Integrated Low R_DS(ON)Upper and Lower MOSFET

Switches: 80mΩ and 60mΩ

Current Mode PWM Operation

Fixed Frequency : 1.2MHz

Other features include internal soft-start, chip enable, over-

voltage, under-voltage, over-temperature and over-current

protections. The uP1728 is available in a space-saving

WDFN3x3-10L package.
