TYPICAL CHARACTERISTICS
Output Voltage Tolerance (Full Load)
• 5 volt output models
±0.25
• 15 volt output models
±0.5
Line Regulation
• Output is directly proportional to input voltage.
Output Voltage Temperature Coefficient
• 0.02%/°C maximum
Converter Frequency
• 100 kHz typical
Isolation
• 100 megohm minimum at 500 V
Note
1.Pins 14 and 15 are connected inter-
nally on single output models.
Notes
1.Nominal output voltage is correct only for nominal input voltage. Output voltage changes in proportion to input voltage.
2.Output ripple results require the connection of a tantalum capacitor (22 μF minimum) across each output.
