This application note is an attempt to explain how to translate datasheet information and apply it to a system level board design. Input Capacitance Although input capacitance value is not critical, the input capacitors must be capable of storing fairly large amounts of energy. This means, for example, small ceramic capacitors would be inappropriate. The primary criteria, though, for choosing the input capacitors is AC ripple current rating. The SIP datasheet contains a chart showing ripple current vs. output current (o r output power). The system designer determines the maximum SIP output current required from the SIP. Based on that number, the chart will show a corresponding ripple current rating the designer needs to plan for when choosing input capacitors. Example using SIP S151-05 for 1.5 V output: The designer knows the S151 output current will be maximum 12.5A in his application. The ripple current chart (5V input) shows a 7A rating required for the input capacitor. Also known is that the capacitor the designer hopes to use has a ripple current rating o f 3A. Therefore, the designer must use three of the chosen capacitors in parallel for a total ripple current capab ility of 9A. This will adequately cover the 7A need. Output Capacitance The only requirement for capacitance value is for basic circuit stability of the SIP. That value is specified on the SIP datasheet—usually 150µF. The other consideration for the output capacitor is the total ESR (Equivalent Series Resistance). As with ripple current, every capacitor has a specified ESR. When using multiple capacitors in parallel, this ESR is added exactly like parallel resistors. Therefore, more capacitors mean less ESR. The SIP datasheet specifies a maximum total ESR necessary for optimum SIP performance. The designer may also choose to add more capacitance to reduce output ripple and noise. Example : The datasheet specifies a maximum ESR of 100m Ω for output capacitance. The system designer wants to use a capacitor with a specified ESR of 130m Ω. Since 130m Ω is more than the needed 100m Ω, two capacitors must be used in parallel for a total effective ESR of 65m Ω. Generally, good, low ESR bulk capacitors are recommended for both input and output capacitance so that fewer capacitors are needed since board real estate is usually an important factor in today's designs.

Instructions for use are available from: www.cdtechno-cps.com Impact on Output Voltage Ripple and Transient Response If the customer’s application requires a very low output voltage ripple and / or very low output voltage overshoot / undershoot during transients, then the guidelines previously shown need to be exceeded and good layout practices become mandatory. By using four 330µF OSCON capacitors, each having ESR = 17m Ω, the output voltage ripple can be decreased to 50mVpk-pk on a 1.2V output SIP. Also during a transient load condition (load current steps from 20% to 100% and back, at 2 A / µsec) the output voltage does not overshoot / undershoot more than 100mV. When fast and deep transient loads are expected, the input capacitor becomes important as well, especially if the SIP is far from its input voltage source. Capacitors having as much as 2000µF and combined ESR lower than 20m Ω might be needed. Practical results heavily depend on physical layout and specific load conditions. For critical applications the customer is encouraged to consult with the manufacturer.
