Design reference
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.

5. Application of Trim and calculation of Trim resistance
4. 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:
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
