External modulation inputs act on V
outputs to superimpose an external 22 kHz signal. Need DC
decoupling to the AC source. If not used they can be left
floating.
DC-DC converters power grounds.
To be connected with power grounds and to the ground layer
through vias to dissipate the heat.
Analog circuits grounds.
Needed for internal pre-regulator filtering. The BYP pin is
intended only to connect an external ceramic capacitor. Any
connection of this pin to external current or voltage sources
may cause permanent damage to the device.
Two I²C addresses available for each section by setting the
Address pins voltage level. See address pin characteristics
table.
The resistors “R
the linear regulators current limit protection threshold by the
equation: I
To be left floating. Do Not connect to GND.
