uP9617

1MHz, 2.0A, High-Efficiency

Synchronous-Rectified Buck Converter

Features

General Description

The uP9617 is a high efficiency synchronous-rectified buck

converter with internal power switches. Fixed 1MHz PWM

operation allows possible smallest output ripple and

external component size. With high conversion efficiency

and small package, the uP9617 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 2.0A Output Current

Accurate Reference: 0.6V ( 1.5%)

Up to 95% Conversion Efficiency

Low Quiescent Current

Integrated Low R_DS(ON)Upper and Lower

MOSFET Switches: 100mΩ and 85mΩ

With internal low R_DS(ON)switches, the uP9617 is capable

of delivering 2.0A output current over a wide input voltage

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

from 0.6V to V_INby a voltage divider. Other features include

internal soft-start, chip enable, over-voltage, under-

voltage, over-temperature and over-current protections.

The uP9617 is available in a space-saving WQFN3x3-16L

package.
