ATW28XXS Series

ATW2815S

Notes to Specifications

1

Parameter guaranteed by line and load regulation tests.

2

Bandwidth guaranteed by design. Tested for 20kHz to 2.0MHz.

3

For operation at 16 Vdc input, derate output power by 33%.

4 Capacitive load may be any value from 0 to the maximum limit without compromising 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.

5

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.

6

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.

7

Load step transition time between 2.0

µs and 10µs.

8

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

9

Input step transition time between 2.0

µs and 10µs.

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

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