QPO-1-EVAL5

The QPO-1-EVAL5 is designed to allow full testing of the QPO-1 and its various performance settings to optimize final system design. The board QPO-1-EVAL5 offers switch settings for the user to select preset values for the Rhr, Rsc, and Rsa resistors. Solder pads are available to mount user-selected values of these components if required. Please refer to the QPO-1 product data sheet and the following pages for the proper application of this board. The EVAL5 accommodates Vicor's Mini DC-DC converters with an input up to 72 Vdc.

The QPO-1-EVAL5 output ripple attenuator SiP uses active filtering to reduce output ripple and noise (PARD) over 20 dB from 50 Hz to 500 kHz. The QPO-1-EVAL5 operates over a voltage range from 3 to 30Vdc 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-EVAL5 improves transient response and ensures precise point-of-load regulation.

Other eval boards of QPO-1-EVAL5 (see www.picorpower.com) allow easy evaluation with other DC-DC converters or power supplies with standard terminations.
