DC/DC ConverterURF1D_QB-100W Series2. Typical application If not using our Mornsun's recommended circuit, please ensure an 100 u F electrolytic capacitors in parallel with the input, which used to suppress the surge voltage come from the input 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...

DC/DC ConverterURF1D_QB-100W Series The maximum load operating power of power supply module at a certain ambient temperature can be calculated by the power dissipation, Formula is as follows: (n is converter efficiency) Therefore, customers can according to the actual application to choose the right heatsink. Applied circuits of Trim (Part in broken line is the interior of models) Calculation formula of Trim resistance: Vo'-Vref Vref Value for R1, R2, R3, and Vref refer to the above table 1.
