AHV28XX Series

Notes to Specifications (Triple Output Models)

Specifications (Triple Output Models) - continued

1.

Tested at each output.

2.

Parameter guaranteed by line and load regulation tests.

3.

At least 25 percent of the total power should be taken from the (+5 volt) main output.

4.

Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.

5.

An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit

protection and is the condition of maximum power dissipation.

6.

Capacitive load may be any value from 0 to the maximum limit without affecting dc performance. A capacitive load in excess of the

maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a

short circuit during turn-on.

7.

Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be

guaranteed to the limits specified.

8.

Above 125

°C case temperature, derate output power linearly to 0 at 135°C case.

9.

Load step transition time between 2 and 10 microseconds.

10. Recovery time is measured from the initiation of the transient to where V

load.

11. Input step transition time between 2 and 10 microseconds.

12. Turn on delay time measurement is for either a step application of power at input or the removal of a ground signal from the inhibit

pin (pin 8) while power is applied to the input.

Notes to Specifications (Dual Output Models)

1.

Tested at each output.

2.

Parameter guaranteed by line and load regulation tests.

3.

Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.

4.

Total power at both outputs.

5.

When operating with unbalanced loads, at least 25% of the load must be on the positive output to maintain regulation.

6.

Capacitive load may be any value from 0 to the maximum limit without affecting dc performance. A capacitive load in excess of the

maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a

short circuit during turn-on.

7.

Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be

guaranteed to the limits specified.

8.

An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit

protection and is the condition of maximum power dissipation.

9.

pin (pin 2) while power is applied to the input.

13. Above 125

°C case temperature, derate output power linearly to 0 at 135°C.
