Lines must be kept as short as possible. 2. If the sense function is not used for remote regulation the user must connect the +Sense to + Vo and -Sense to 0V at the DC-DC converter pins and will compensate for voltage drop across pins only. 3. The connections between Sense lines and their respective power lines must be kept as short as possible, otherwise they may be picking up noise, interference and/or causing unstable operation of the power module. Figure 6 Note: 1. In cables and discrete wiring applications, twisted pair or other techniques should be implemented. 2. PCB-tracks or cables/wires for Remote Sense must be kept as short as possible. 3. Using remote sense with long wires long wires may cause unstable operation. Note that large wire impedance may cause oscillation of the output voltage and/or increased ripple. Consult technical support or factory for further advice of sense operation. 4. We recommend using adequate cross section for PCB-track layout and/or cables to connect the power supply module to the load in order to keep the voltage drop below 0.3V and to make sure the power supply's output voltage remains within the specified range cui.com Additional Resources: Product Page | 3D Model | PCB Footprint CUI Inc │ SERIES: PRQ75W-D │ DESCRIPTION: DC-DC CONVERTER date 10/14/2022 │ page 11 of 11 REVISION HISTORY rev. description date 1.0 initial release 01/29/2021 1.01 trim resistor equations and figures updated 10/14/2022 The revision history provided is for informational purposes only and is believed to be accurate.
