Crane Aerospace & Electronics Power Solutions www.DataSheet4U.com 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...
