Notes:
1. Using remote sense with long wires may cause output voltage to become unstable. Consult us if long sensing wiring is necessary.
2. Sense tracks or wires should be as short as possible. If using wires, it should not use twisted-pair or shielded wires.
3. Please use wide PCB tracks or a thick wires between the power supply module and the load, the line voltage drop should be kept less
than 0.3V. Make sure the power supply module's output voltage remains within the specified range.
4. The impedance of wires may cause the output voltage oscillation or a greater ripple, please take adequate assessments before using.

2. Typical application
If not using Momsun’s recommended cicuit, please ensure an 100 μF electrolytic capacitors in parallel with the input, which used to
suppress the surge voltage come from the iuput terminal.
If it is required to further reduce input&output ripple, properly increase the input & output of additional capacitors Cin and Cout or select
capacitors of low equivalent impedance,provided that the capacitance is no larger than the max. capacitive load of the product.

4. Thermal design
The maximum operating temperature of base-plate TB is 100 ℃, as long as the user's thermal system keeps TB <100 ℃, the converter can
deliver its full rated power. A power derating curve can be calculated for any heatsink that is attached to the base-plate of the converter.
It is onen airflow rate. This information is usually available from the heatsink vendor. The following formula can the be used to determine the
maximly necessary to determine the thermal resistance, Rth(B-A), of the chosen heatsink between the base-plate and the ambient air for a
givum power the converter can dissipate for a given thermal condition if its base-plate is to be no higher than 100 ºC.
