Notes

1. Tc = –55°C to +125°C.

2. Up to 90% of the total output current/power is available from either output

providing the positive output is carrying at least 10% of the total output

power.

3. Operation is limited below 16 V (see Figure 21).

4. Effect

on

the

negative

output

under

the

following

conditions:

5. Effect

on

the

negative

output

under

the

following

conditions:

6. Tested with 3300 pF ceramic bypass capacitors connected externally from

input common to case and output common to case

7. Indefinite short circuit protection not guaranteed above 125°C case.

8. Recovery time is measured from application of the transient to point at which

Vout is within 1% of final value.

9. Transition time

≥ 10 µs.

Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, radiation level O, unless otherwise specified.
