AHF28XX Series

AHF2815S

Notes to Specifications

1. Parameter guaranteed by line and load regulation tests.

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

3. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.

A capacitive 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.

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

Thereafter, parameters shall be guaranteed to the limits specified in Table III.

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. Load step transition time between 2 and 10 microseconds.

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

percent of V

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

9. Turn-on delay time measurement is for either a step application of power at the input or the removal of

a ground signal from the inhibit pin (pin 2) while power is applied to the input is unlimited.
