2 / 16 page  Data Sheet March 27, 2008 QBK025A0B DC-DC Power Modules: 36-55Vdc Input; 12Vdc Output Voltage; 25A Output Current LINEAGE POWER 2 Absolute Maximum Ratings Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability. Parameter Device Symbol Min Max Unit Input Voltage* Continuous VIN -0.3 55 Vdc Non- operating continuous VIN -0.3 75 Vdc Operating Ambient Temperature All TA -40 85 °C (See Thermal Considerations section) Storage Temperature All Tstg -55 125 °C I/O Isolation Voltage (100% factory Hi-Pot tested) All ⎯ ⎯ 1500 Vdc * Input over voltage protection will shutdown the output voltage when the input voltage exceeds threshold level. Electrical Specifications Unless otherwise indicated, specifications apply over all operating input voltage, resistive load, and temperature conditions. Parameter Device Symbol Min Typ Max Unit Operating Input Voltage VIN 36 48 55 Vdc Maximum Input Current IIN,max - - 9.5 Adc (VIN=0V to 55V, IO=IO, max) Inrush Transient All I 2t - - 1 A 2s Input Reflected Ripple Current, peak-to-peak (5Hz to 20MHz, 12μH source impedance; VIN= 48V, IO= IOmax ; see Figure 9) All - 24 - mAp-p Input Ripple Rejection (120Hz) All - -50 - dB CAUTION: This power module is not internally fused. An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 15A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information. |
