(1)

Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account

separately.

(2)

TPS2223A, TPS2224A, TPS2226A: two switches on. TPS2220A: one switch on.

(3)

Specified by design; not tested in production.

(4)

From application of short to 110% of final current limit.
