When Remote Sense is not used 1. Ripple & noise All the 100QBR_24S3 series have been tested according to the following recommended test circuit before leaving the factory. 2. Typical application If don’t use our company’s EMC models, please make sure the input of at least 33uF electrolytic capacitor in parallel to suppress the input terminal may produce surge voltage. If it is required to further reduce input and 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. 2.

Thermal design The maximum operating temperature of base- plate TB is 100°C, as long as the user‘s thermal system keeps TB <100°C, 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 only necessary to determine the thermal resistance, Rth(B-A), of the chosen heatsink between the base-plate and then ambient air for a given air- flow rate. This information is usually available from the heatsink vendor. The following formula can the be used to determine the maximum power the converter can dissipate for a given thermal condition if its base-plate is to be no higher than 100 ºC. 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: 5. Application of Trim and calculation of Trim resistance Calculation formula of trim resistance: Note: Value for R1, R2, R3, and Vref refer to the above table 1. RT: Resistance of Trim. a: User-defined parameter, no actual meanings. Vo’: The trim up/down voltage. 6. The product does not support in parallel and hot-plug use 3.
