22, 23

Not connected

AGND/VL-

Analog ground and connection of the bypass capacitor of VL-

SET

Input pin for the reference voltage to set the higher limit for the temperature compensation for

VOFFE

Input pin for the NTC temperature sensor

FB5

Feedback pin for the negative buck-boost converter VOFFE

28, 29

Not connected

SW5

Switch pin for the negative buck-boost converter generating VOFFE

VIN3

Input supply for the buck-boost converter generating VOFFE
