Peak output current lasting less than 60 seconds with duty cycle ≤10%.

During peak loading, outputs may exceed total regulation limits.

Total regulation is defined as the static output regulation at 25 °C, including

initial tolerance, line voltage within stated limits, load currents within stated

limits, and output voltages adjusted to their factory settings. Also, for

6

Pins 10 and 11 are a floating output, which can be referenced as either

positive or negative. Pin 10 is positive with respect to pin 11. Either pin 10

or 11 must be connected to return (pins 4-7) for proper operation.

Derating curve is application specific for ambient temperatures > 50 °C, for

optimum reliability, no part of the heatsink should exceed 110 ºC and no

semiconductor case temperature should exceed 115 ºC.

Caution: Allow a minimum of 1 second after disconnecting the power when

making thermal measurements.
