DESCRIPTION
The MHP270 SeriesTM DC/DC converters provide up to 65 watts of output power over the full -55C to 100C temperature range. MHP270 models operate from a MIL-STD-704 nominal 270 volt DC power bus - from 160 to 400 VDC continuous operation with surges to 450 volts - 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. MHP270 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. Up to five single output MHP 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 85% current sharing accuracy over all loading conditions. MHP Series of converters feature a flexible synchronization scheme in which units may be synchronized to an external clock or to one another by using sync in and sync out pins provided on each unit. MHP converters have a nominal switching frequency of 600 kHz, but may be synchronized at any frequency from 525 to 675 kHz. MHP converters meet a wide variety of military/aerospace performance and environmental specifications. Their continuous operation input voltage (160 to 400) meets the normal operating limits of MILSTD-704. The unit shuts down above approximately 425 volts, but it is rated to withstand a surge of up to 450 volts for 50 msec. The units are built as fully hermetic thick film hybrids in Interpoint's MILSTD-1772 certified facilities. The MHP270 Series offer a complete list of standard features which include: Undervoltage lock-out - shuts down when the input line voltage falls below approximately 120 VDC to provide smooth initialization. Continuous short circuit protection - current limit set at approximately 125%. Soft-start - controlled start-up at turn-on, release from inhibit, and recovery from load fault conditions. Remote sense - to provide automatic compensation for voltage drops on output lines on single output models.
