Description

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 QPO-1-EVAL1 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.

The QPO-1-EVAL1 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-EVAL1 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 of QPO-1-EVAL1 improves transient response and ensures quiet point-of-load regulation when used in conjunction with the power supply's control loop or trim node.
