Output Power
• 60 to 70 watts depending on model
Lead Soldering Temperature (10 sec per lead)
• 300°C
Storage Temperature Range (Case)
• –55°C to +125°C
Output Voltage Temperature Coefficient
• 150 ppm/°C, typical
Input to Output Capacitance
• 160 pF, typical
Isolation
• 100 megohm minimum at 500 V
Conversion Frequency
• Free run mode 245 kHz, typical
Inhibit Pin Voltage (unit enabled)
• 4.5 to 5.5 V
Sync In (245 to 370 kHz.)
• Duty cycle 70% min, 98% max.
• Logic low 0.8V max
• Logic high 4.5 V min
• Referenced to input common
• If sync is not used, leave unconnected
Inhibit TTL Open Collector
• Logic low (output disabled)
Inhibit pin current 1 mA max
• Referenced to input common
• Logic high (output enabled)
V =
4.5V
Temperatures are referenced to the temperature at the converter’s baseplate
• Linearly derate output power/current from 100% at 85°C to 0% at 125°C.
• Above 105°C linearly derate steady state input voltage to 33 volts at 125°C.
• Indefinite short circuit protection is not guaranteed above 85°C case.
• Operation below an input voltage of 19 volts, including operation in MIL-
STD-704E emergency power conditions, is possible with derated output
power. See Figures 10 and 11.
Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
Input Voltage Range
• 19 to 40 VDC continuous (see Derating)
Case Operating Temperature (Tc)
• –40°C to +85°C full power
