uP1727

1.0MHz, 3.0A, High-Efficiency

Synchronous-Rectified Buck Converter

Features

General Description

The uP1727 is a high efficiency synchronous-rectified buck

converter with internal power switches. Fixed 1.0MHz

PWM operation allows possible smallest output ripple and

external component size. With high conversion efficiency

and small package, the uP1727 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 uP1727 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: 70mΩ and 50mΩ

Current Mode PWM Operation

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

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

protections. The uP1727 is available in a space-saving

WDFN3x3-10L and PSOP-8L packages.

Fixed Frequency : 1.0MHz

100% Maximum Duty Cycle for Lowest Dropout

Internal Soft-Start

Over Voltage and Under Voltage Protection

Over Temperature and Over Current Protection
