Crane Aerospace & Electronics Power Solutions MHp270 single and dual dc/dc converters 270 Volt input – 65 Watt Features parallel operation with current share, up to 5 units (276 watts) • operating range -55° to +100°C • Input voltage 160 to 400 VDC • Transient protection 450 V for 50 ms • Fully isolated, magnetic feedback • Fixed high frequency switching • Remote sense on single models • Sync In and Sync out • Inhibit primary side and secondary side VDC Output single MoDELS • Indefinite short circuit protection • High power density, up to 85% efficiency 5 12 15 28 Dual ±5 ±12 ±15 description The MHP270 Series™ DC/DC converters provide up to 65 watts of output power over the full –55°C to 100°C 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. The converters are available with standard screening or “ES” screening 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 MHP270 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 an 85% current sharing accuracy over 35% load to full load conditions. MHP270 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. MHP270 converters have a nominal switching frequency of 525 kHz, but may be synchronized at any frequency from 475 to 575 kHz. MHP270 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 MIL-STD-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 our MIL-PRF-38534 certified facilities. Features 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.
