DESCRIPTION The SMHP120TM Series DC/DC converters provide up to 65 watts of output power over the full -55 to 125C temperature range. SMHP120 models operate from a MIL-STD-704 nominal 120 volt DC power bus - from 80 to 175 VDC - continuous operation and provide isolated outputs at 5, 12, 15, and 28 VDC. Parallel operation for all loading conditions is supported without any requirement for external components. PARALLEL OPERATION Up to five single output SMHP converters may be used in parallel to power a single load by simply connecting the share pins of all units. Units in this configuration have a 90% current sharing accuracy over all loading conditions, and provide true n+1 operation. FEATURES Synchronization - units may be synchronized to an external clock or to one another by using sync in and sync out pins provided on each unit. The converters have a nominal switching frequency of 600 kHz, but may be synchronized at any frequency from 525 to 675 kHz. Low voltage lock-out - shuts down when the input line voltage falls below approximately 50 VDC to provide smooth initialization. Continuous short circuit protection - using foldback current limit set at approximately 125%. Soft-start - at both turn-on and recovery after load fault conditions. Remote sense - to provide automatic compensation for voltage drops on output lines on single output models. For more information, contact your Interpoint representative listed in Section A5. SCREENING SMHP120 converters offer three screening options - Standard, or Class H. See Section C2, Quality Assurance, pages C2-7 through C2-9, for descriptions. CONVERTER DESIGN SMHP120 DC/DC converters are constant frequency, pulse width modulated switching power supplies which use a quasi-square wave, two-switch single-ended forward converter design. Tight load regulation is achieved through a wide-bandwidth magnetic feedback circuit. SMHP converters meet a wide variety of military/aerospace performance and environmental specifications. Their continuous operation input voltage (80 to 175) meets the normal operating limits of MIL-STD-704D. The units are built as fully hermetic thick film hybrids in Interpoint's MIL-STD-1772 certified facilities.
