... MOSFET is a square wave of duty cycle V primary function of the input capacitor is to provide a low impedance loop for the edges of pulsed current drawn by the EUP3412. A low ESR input capacitor sized for the maximum RMS current must be used. The size required will vary depending on the load, output voltage and input voltage source impedance characteristics. A typical value is around 22µ ...

... The external resistive divider is connected to the output, allowing remote voltage sensing as shown below. Thermal Considerations To avoid the EUP3412 from exceeding the maximum junction temperature, the user will need thermal analysis. The goal of the thermal analysis is to determine whether the operating conditions exceed the maximum junction temperature of the part ...
