SVTR2800S Series HIGH RELIABILITY HYBRID RADIATION TOLERANT DC-DC CONVERTERS DESCRIPTION The SVTR series of high reliability DC-DC converters is operable over the full military (-55 °C to +125 °C) temperature range with no power derating. Paramount to the SVTR series is a magnetic feedback circuit that is radiation immune. Operating at a nominal fixed frequency of 475 k Hz, these regulated, isolated units utilize well controlled undervoltage lockout circuitry to eliminate slow start-up problems. The SVTR series has been characterized and tested for TID (Total Ionizing Dose) at HDR (High Dose Rate) and LDR (Low Dose Rate - ELDRS) per VPT’s RHA plan. The SVTR series has also been characterized for SEE (Single Event Effects). VPT's certified radiation program per MIL-PRF-38534, Appendix G is currently under review by DSCC. Please contact DSCC at 614-692-0585 for details. This characterization and testing is performed at the critical semiconductor ponent piece-part level (RLAT) from traceable semiconductor lots as well as on the SVTR series hybrid converter level produced from the same traceable semiconductor lots evaluated during RLAT. These converters are designed and manufactured in a facility qualified to ISO9001 and certified to MIL-PRF38534 Class H and Class K and MIL-STD-883.
