Figure 21. Margin Up/Down Application Schematic
MARGIN UP/DOWN NOTES
1. The Margin Up and Margin Down controls were not intended to be activated simultaneously. If they are their
affects on the output voltage may not completely cancel, resulting in the possibility of a slightly higher error in
the output voltage set point.
2. The ground reference should be a direct connection to the module GND at pin 7 (pin 1 for the PTHxx050).
This will produce a more accurate adjustment at the load circuit terminals. The transistors Q1 and Q2 should
be located close to the regulator.
3. The Margin Up and Margin Down control inputs are not compatible with devices that source voltage. This
includes TTL logic. These are analog inputs and should only be controlled with a true open-drain device
(preferably discrete MOSFET transistor). The device selected should have low off-state leakage current.
Each input sources 8 A when grounded, and has an open-circuit voltage of 0.8 V.
