Absolute maximum ratings
(Voltages relative to GND unless otherwise stated)
DC-DC converter
High-side current monitor
Switching NPN transistor
These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Operation at the
absolute maximum ratings for extended periods may reduce device reliability.
