... 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 EUP3408. 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 4.7µ ...
