Natural convection cooling, 40 W maximum.
Forced air, 20 CFM at 1 atmosphere, 50 W maximum.
Peak output current lasting less than 30 seconds with duty cycle less than 10%.
During peak loading, outputs may go outside of total regulation limits. Peak
total power must not exceed 60 W.
50 MHz bandwidth, peak-to-peak, measured differentially.
Total regulation is defined as the static output regulation at 25 °C, including
initial tolerance, load currents within stated limits, and output voltages
adjusted to their factory settings. Also, 0.25 ² I
regulation.
A minimum load of 0.5 A is required on the +5 V output to obtain full current
from the negative output.
Single output models have floating outputs which may be referenced as either
positive or negative.
Derating curve is application specific for ambient temperatures > 50 °C, for
optimum reliability no part of the heatsink should exceed 120 °C and no
semiconductor case temperature should exceed 130 °C.
Caution: Allow a minimum of 1 second after disconnecting the power when
making thermal measurements.
