DC/DC CONVERTERS
Electrical Characteristics: -55°C to +125°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
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 17 V (see Figure 19).
4. Effect
on
the
negative
output
under
the
following
conditions:
+Pout 20% to 80%; –Pout 80% to 20%
5. Effect
on
the
negative
output
under
the
following
conditions:
+Pout 50%; –Pout 10% to 50%
6. Indefinite short circuit protection not guaranteed above 125°C case.
7. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
8. Transition time
≥ 10 µs.
9. Parameter shall be tested as part of device characterization and after design
and process changes. Thereafter, parameters shall be guaranteed to the
limits specified in the electrical Characteristics table.
