Interpoint model numbers use an “O” in the RHA designator position to indicate the “-” (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as “no RHA”. See Screening Tables 1, 2 and 3 for more information. Available configurations: OO, HP, HR, KP, KR, KF synC and inhibit sync Input frequency 270-330 kHz • Duty cycle 20% min, 80% max • 2.5 V p-p minimum amplitude • 10 V p-p maximum amplitude • Sync circuit is floating and isolated • If sync is used at lower end of the range, full load • operation is not guaranteed. Inhibit Active low (output disabled) • InH referenced to input common ‣ Active low, pulled to 0.4 V or lower ‣ Inhibit pin current ‣ < 2mA Active high (output enabled) • High >2.4V ‣ not to exceed 10V ‣ Open pin voltage 5 to 6 volts ‣ Crane Aerospace & Electronics Power Solutions www.interpoint.com Page 3 of 19 sMrt28 single, Dual and triple space Dc/Dc converters 28 VOLt Input – 35 Watt – space quaLIFIeD SMRT28 Rev E - 20100216 |
