T o trim down to 0.6V, units with an initial output voltage of up to 1.2V can be used. • T rim m ing U P — raising the output voltage using a resistor from Trim to G round. 3 .3Vin 5Vin Rtrim = 1992 (Vout − Vset ) Rtrim = − 500 × (1 + Vset − Vout ) (Vset − Vout ) V out max = 2 .5V • V out max = V set + 1 a s R trim a pproaches 0 Ω . T rim m ing D O W N — lowering the output voltage using a resistor from T rim to an external voltage reference or to the Vout pins. 3 .3Vin 5Vin Rtrim = 498 × V out min = 0 .5V ( 4 − 5 × Vref ) (Vout − Vset ) Rtrim = − 500 × (− 1 − Vset + Vout + Vref ) (− Vset + Vout ) V out min = V set – ( Vref – 1) as R trim a pproaches 0 Ω . W here: V out is the desired output voltage. V set is the output voltage setpoint (output voltage without trim ). V ref is the reference voltage for the trim resistor when trim m ing down. If using V ou t f or this purpose, then V ref = V out . R trim is the resistance value of the trim resistor (ohm s). 1150 Eglinton Avenue East Toronto, Ontario M3C 1H7 1-866-740-1232 S111_084-S111-00_RevG_Jan18-2005.fm www.cdtechno-cps.com 4607 S.E.

This application note is an attem pt to explain how to translate datasheet inform ation and apply it to a system level board design. I nput Capacitance A lthough input capacitance value is not critical, the input capacitors m ust be capable of storing f airly large am ounts of energy. This m eans, for exam ple, sm all ceram ic capacitors would be inappropriate. The prim ary criteria, though, for choosing the input capacitors is AC ripple c urrent rating. The SIP datasheet contains a chart showing ripple current vs. output current (o r o utput power). The system designer determ ines the m axim um SIP output current required from t he SIP. Based on that num ber, the chart will show a corresponding ripple current rating the d esigner needs to plan for when choosing input capacitors. E xam ple u sing SIP S111-03 for 1.2 V output: The designer knows the S111 output current will be m axim um 8 A in his application. The ripple current chart (3.3V input) shows a 5 A rating required for the input capacitor. A lso known is that the capacitor the designer hopes to use has a ripple current rating o f 3 A. Therefore, the designer m ust use two of the chosen capacitors in parallel for a tota l r ipple current capability of 6A. This will adequately cover the 5 A need. O utput Capacitance T he only requirem ent for capacitance value is for basic circuit stability of the SIP. That value is s pecified on the SIP datasheet— usually 150µF. The other consideration for the output c apacitor is the total ESR (Equivalent Series Resistance). As with ripple current, every c apacitor has a specified ESR. W hen using m ultiple capacitors in parallel, this ESR is added e xactly like parallel resistors. Therefore, m ore capacitors m ean less ESR. The SIP datasheet s pecifies a m axim um total ESR necessary for optim um SIP perform ance. The designer m ay a lso choose to add m ore capacitance to reduce output ripple and noise. E xam ple : The datasheet specifies a m axim um ESR of 100m Ω f or output capacitance. The system d esigner wants to use a capacitor with a specified ESR of 130m Ω . Since 130m Ω is m ore than the needed 100m Ω , two capacitors m ust be used in parallel for a total effective ESR of 65m Ω . G enerally, good, low ESR bulk capacitors are recom m ended for both input and output c apacitance so that fewer capacitors are needed since board real estate is usually an im portant f actor in today's designs. 1150 Eglinton Avenue East Toronto, Ontario M3C 1H7 1-866-740-1232 S111_084-S111-00_RevG_Jan18-2005.fm www.cdtechno-cps.com 4607 S.E.

B y using four 330 µ F O S C O N capacitors, each having E S R = 17 m Ω , the output voltage r ipple can be decreased to 50 m V pk-pk on a 1.2V output S IP . A lso during a transient load c ondition (load current steps from 20% to 100% and back, at 2 A / µ sec) the output voltage d oes not overshoot / undershoot m ore than 100m V. W hen fast and deep transient loads are expected, the input capacitor becom es im portant as w ell, especially if the SIP is far from its input voltage source. C apacitors having as m uch as 2 000 µ F and com bined E SR lower than 20 m Ω m ight be needed. P ractical results heavily depend on physical layout and specific load conditions.
