Electrical Performance Characteristics - continued Notes to Specifications ATW2815D 1 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. 2 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 8) while power is applied to the input. 3 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. 4 Above +125 °C case, derate output power linearly to 0 at +135°C case. 5 Input step transition time between 2.0 µs and 10µs. 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 will interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn on. 7 Load step transition time between 2.0 µs and 10µs. 8 Bandwidth guaranteed by design. Tested for 20KHz to 2MHz. 9 Load current split equally between +V OUT and –VOUT. 10 When operating with unbalanced loads, at least 25% of the load must be on the positive output to maintain regulation. 11 Parameter guaranteed by line and load regulation tests. 12 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 II. 13 Up to 90% of full power is available from either output provided the total output does not exceed 30W.
