Resistor Trim Equations
N O T E:
•
For best results, the trim m ing range should not exceed +/-20% of the initial
output voltage set by the factory (Vset). T o trim down to 0.6V, units with an
initial output voltage of up to 1.2V can be used.
Trim m ing U P— raising the output voltage using a resistor from Trim to G round.

Rtrim = − 500 ×
(1 + Vset − Vout )
(Vset − Vout )
Vout max = Vset + 1 as R trim
approaches 0Ω .
Trim 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.

Vout min = Vset – (Vref –1) as R trim
approaches 0Ω .

Vout is the desired output voltage.
Vset is the output voltage setpoint (output voltage without trim ).
Vref is the reference voltage for the trim resistor when trim m ing down. If using Vout
for this purpose, then Vref = Vout.
R trim is the resistance value of the trim resistor (ohm s).

External Capacitance for SIP Products
All SIP products require external capacitance to be placed on the system board that the SIP will
be designed into. This application note is an attem pt to explain how to translate datasheet
inform ation and apply it to a system level board design.
Input Capacitance
Although input capacitance value is not critical, the input capacitors m ust be capable of storing
fairly 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
current rating. The SIP datasheet contains a chart showing ripple current vs. output current (or
output power). The system designer determ ines the m axim um SIP output current required from
the SIP. Based on that num ber, the chart will show a corresponding ripple current rating the
designer needs to plan for when choosing input capacitors.
Exam ple using 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.
Also known is that the capacitor the designer hopes to use has a ripple current rating of
3A. Therefore, the designer m ust use two of the chosen capacitors in parallel for a total
ripple current capability of 6A. This will adequately cover the 5 A need.
Output Capacitance
The only requirem ent 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. W hen using m ultiple capacitors in parallel, this ESR is added
exactly like parallel resistors. Therefore, m ore capacitors m ean less ESR. The SIP datasheet
specifies a m axim um total ESR necessary for optim um SIP perform ance. The designer m ay
also choose to add m ore capacitance to reduce output ripple and noise.
Exam ple:
The datasheet specifies a m axim um 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
m ore than the needed 100m Ω, two capacitors m ust be used in parallel for a total
effective ESR of 65m Ω.
Generally, good, low ESR bulk capacitors are recom m ended for both input and output
capacitance so that fewer capacitors are needed since board real estate is usually an im portant
factor in today's designs.

Impact on Output Voltage Ripple and Transient Response
If the custom er’s application req uires a very low output voltage ripple and / or very low
output voltage overshoot / undershoot during transients, then the guidelines previously
show n need to be exceeded and good layout practices becom e m andatory.
B y using four 330 µ F O S C O N capacitors, each having E S R = 17 m Ω , the output voltage
ripple can be decreased to 50 m V pk-pk on a 1.2V output S IP . A lso during a transient load
condition (load current steps from 20% to 100% and back, at 2 A / µ sec) the output voltage
does 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
2000 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. For critical
applications the custom er is encouraged to consult with the m anufacturer.
