ABB QBDE067A0B641-02PHZ

The QBDE067A0B Barracuda series of dcdc converters is a new generation of fully regulated DC/DC power modules designed to support 12.0Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load (POL) converters, as well as other application requiring a tightly regulated output voltage. The QBDE067A0B series operate from an input voltage range of 40 to 60Vdc and provide up to 800W output power with a fully regulated output voltage of 72.0Vdc in an industry standard, DOSA compliant quarter brick. The converter incorporates digital control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve full load efficiency exceeding 96.3% at 12.0Vdc output. This leads to lower power dissipation such that for many applications a heat sink is not required. Standard features include a heat plate to attach external heat sinks or contact a cold wall, on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout and PMBus interface. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering.
