QSVW042A0B641-HZ

The QSVW042A0B Barracuda series of dc-dc converters are a new generation of DC/DC power modules designed to support 9.6 - 12Vdc 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 QSVW042A0B series operate from an input voltage range of 36 to 75Vdc, and provide up to 42A output current at output voltages from 6.0Vdc to 12.0Vdc. The 12V output is well regulated for the entire input voltage range. The QSVW042A0B has improved line transient performance as compared to earlier generation modules. The converter incorporates digital control, synchronous rectification technology, and innovative packaging techniques to achieve efficiency reaching 96% peak at 12Vdc output. This leads to lower power dissipations such that for many applications a heat sink is not required. Standard features include output voltage trim, remote sense, on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout.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.
