3.1 MODE Pin Configuration

The TPS563212 has a MODE pin that can offer two different states of operation under light load conditions, and offer two options for the function of Pin 1.

Table 3-1 MODE Pin Settings
MODE RESISTOR RANGE RECOMMENDED MODE RESISTOR VALUE OPERATION MODE in LIGHT LOAD FUNCTION of PG/SS PIN
[0, 12] kΩ 0 Eco-mode Power Good(1)
[30, 50] kΩ 47 kΩ Eco-mode Soft Start
[83, 120] kΩ 100 kΩ FCCM Soft Start
[180, ∞] kΩ Float FCCM Power Good
(1) Connect pin 1 to GND to get a better thermal performance if the PG was not used when PG function was selected.
