FIGURE 2.6 TRIGGER CONFIGURATION
ZERO-VOLT LOADING CONNECTION
The Electronic Loa d can be connected in se ries with volta ge sources tha t ca n a ccommoda te the minimum opera ting
volta ge a nd line volta ge drop so the Electronic Loa d ca n test the devices at its full cu rrent ca pa city down to a zero -volt
level.
Important Notes:
1. The boost power supply used for Zero-Vo lt Loa d Opera tion must ha ndle up to the ma ximum opera ting current of
the a pplica tion.
2. The power ra ting of the Load Ba nk will decrea se ba sed on the amount of power dissipa ted at the boost power
supply.
3. A protective diode ra ted for the ma ximum operating current of the applica tion will need to be pla ced across the
power termina ls of the DUT.
4. A boost power supply with minima l noise specifica tion is recommended for zero -volt loa d opera tion.
