notes:
all temperatures refer to case temperature, t
c
.
1. guaranteed by design, not tested.
2. Specified at 50% load.
3. With a series inductor on the Vin power lead (L
in
= 6 µH).
4. Maximum duration of short circuit: 90 seconds at 25°C, 30 seconds at 125°C.
5. Load fault is a short circuit into 1 . Recovery is into resistive full load.
6. Transition > 10 µs.
7. Measured from release of inhibit until Vout settles to within 1% of final value at full
load with Vin at 28V.
8. Recovery = time to settle to within 1% of Vout final value.
