QuietPower^™

QPO Evaluation Board

Description

Features QPO-1

• >30 dB PARD attenuation, 1 kHz to 500 kHz

• 3-30 Vdc operating range

• 10A rating

The QPO-1-EVAL1 kit is designed to allow full

testing of the QPO-1 and the various performance

options to optimize a final system design. The board

offers two terminal options for vertical or

horizontal mounting. The user must select the

required values for the Rhr, Rsc and Rsa resistors

and solder them in the designated positions before

applying power to the EVAL1. Please refer to the

QPO-1 product data sheet, schematics and the

following pages for the proper application of this

board.

• Supports precise point-of load regulation

• 90-99% efficiency

• User selectable performance optimization for

Attenuation, power dissipation, transient response

• 1.0 x 1.0 x 0.2" SiP

• LGA mounting

The QPO-1 output ripple attenuator SiP uses active

filtering to reduce output ripple and noise (PARD)

over 20 dB from 500 Hz to 500 kHz and can be

extended down to 50 Hz with additional

capacitance added to the VREF pin. The QPO-1

operates over a voltage range from 3 to 30 Vdc and

supports load currents as high as 10A. Output

regulation is maintained with remote sense or trim

adjustment of the power supply. The closed loop

architecture improves transient response and

ensures quiet point-of-load regulation when used in

conjunction with the power supply’s control loop or

trim node.

• Closed control loop improves transient response of

most DC-DC converters and power supplies

• Reduces required number of output capacitors to

support dynamic loads.

• Evaluation board includes Johnson Jack for low-

noise measurement of QPO performance.
