Application Note AN 2014-06
V1.1 January 2015
10 Test report
All test condition are based on 60°C heat sink temperature.
For the efficiency test it is important to take the voltage sensing on the input and output power with the
Vin_sense and Vout_sense right beside the power connections.

Out of the table one can see, that the full load efficiency is improved by only changing from 3pin to 4pin
configuration. Due to this advantage it can be possible to replace a current 3pin PFC stage with a MOSFET
of one step higher R
DS(on)
. This will help to increase the efficiency all over the power range beside full load at
low line. Therefore it will help to enter into the TITANUM Standard for server SMPS.
