Electrical Performance Characteristics - continued ATW2812D 1 Parameter guaranteed by line, load and cross regulation tests. 2 Up to 90% of full power is available from either output provided the total output does not exceed 30W. 3 Bandwidth guaranteed by design. Tested for 20KHz to 2MHz. 4 Load current split equally between +V OUT and –VOUT. 5 Three-watt load on output under test, 3.0W to 27W load change on other output. 6 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. 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 in Table I. 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 Load step transition time between 2.0 µs and 10µs. 10 Recovery time is measured from the initiation of the transient to where V OUT has returned to within ±1.0% of VOUT at 50%load. 11 Input step transition time between 2.0 µs and 10µs. 12 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 8) while power is applied to the input.
