QPO-1-EVAL1 Data Sheet Rev. 1.2
Page 1 of 4
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.
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.
