Let’s change to: It is recommended to use the circuit shown in Fig. 1 during product testing and application, or otherwise ensure that at least 220 µF of electrolytic capacitors are connected at the input in order to ensure adequate voltage surge suppression and protection. 2. It is recommended to increase the value of Cin and pay attention to the unstable input voltage if the product input side is paralleled with motor drive circuit and/or larger energy transient circuits, to ensure the stability of input terminal and avoid repeatedly start-up problems due to input voltage lower than under-voltage protection point. 3. It is recommended to increase the output capacitance, limited to the capactive load specification and/or increasing the voltage clamping circuit (such as TVS) if the output terminal is inductive device such as relay or a motor, to ensure adequate voltage surge suppression and protection. 4. Input and/or output ripple can be further reduced by appropriately increasing the input & output capacitor values Cin and Cout and/or by selecting capacitors with a low ESR (equivalent series resistance). Also make sure that the capacitance is not exceeding the specified maximum capacitive load value of the product.

If the Trim pin is shorted with + Vo, or its value is too low, the or the output voltage Vo’ would be lower than 0.9Vo, which may cause the product to fail. cui.com Additional Resources: Product Page | CUI Inc │ SERIES: PRQ150W │ DESCRIPTION: DC-DC CONVERTER 3D Model | PCB Footprint date 04/04/2023 │ page 10 of 11 REMOTE SENSE APPLICATION Figure 4 Note: 1. 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 5 Note: 1. In cables and discrete wiring applications, twisted pair or other techniques should be implemented. 2. Using remote sense with long wires may cause unstable output, please contact technical support if long wires must be used 3. PCB-tracks or cables/wires for Remote Sense must be kept as short as possible. Twisted pair or shielded wires are suggested for remote compensation and must be kept as short as possible. 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. 5. Note that large wire impedance may cause oscillation of the output voltage and/or increased ripple. Consult technical sup port or factory for further advice of sense operation. cui.com Additional Resources: Product Page | 3D Model | PCB Footprint CUI Inc │ SERIES: PRQ150W │ DESCRIPTION: DC-DC CONVERTER date 04/04/2023 │ page 11 of 11 REVISION HISTORY rev. description date 1.0 initial release 10/25/2021 1.01 pin connections tables updated 04/04/2023 The revision history provided is for informational purposes only and is believed to be accurate.
