1. Remote Sense Connection if not used
(1) 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.
(2) 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.
2. Remote Sense Connection used for Compensation
(1) PCB-tracks or cables/wires for Remote Sense must be kept as short as possible.
(2) In cables and discrete wiring applications, twisted pair or other techniques should be implemented.
(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.
Design Reference
1. Typical application
(1) We recommened using the recommended circuit shown in Fig.1 during product testing and application,otherwise please ensure that at
least a 220μF electrolytic capacitors is connected at the input in order to ensure adequate voltage surge suppression and protection.
(2) We recommened increasing 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 stablity of input terminal and avoid repeatedly start-up problems due
to input voltage lower than undervoltage protection point.
(3) We recomended increasing the output capacitance with 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
max. capacitive load value of the product.

Note: When using the Trim down function make sure that the RT resistor value is calculated correctly. 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.
