Notes to Specifications
Electrical Performance Characteristics - continued
1
Recovery time is measured from the initiation of the transient to where VOUT 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 ground signal from the
Enable pin (pin 2) 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 a condition of maximum power dissipation.
4
Above +125°C case, derate output power linearly to 0 to +135°C case.
5
Transition time
>10s.
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 may disturb loop stability and may interfere with the operation of the load fault detection circuitry, appearing
as an overload during turn-on.
7
Bandwidth guaranteed by design. Tested for 20KHz to 1.0MHz.
8
Parameter guaranteed by line and load regulation tests.
9
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 this table.
10
Output voltage can be adjusted to the range of 150V to 300V with an external 1KOhms trim pot. The trim pot shall be connected
to pin 5 (Output Adjust 1) and pin 6 (Output Adjust 2).
