The QSW025A0B series are enhanced from their predecessor QBW025A0B series, with improvements to the internal shutdown control, improved response to input voltage transients, and inclusion of output reverse current protection during startup. The QSW025A0B series operate from an input voltage range of 36 to 75Vdc and provide up to 25A output current at 12V in an industry standard quarter brick. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 95% at 12V full load. This leads to lower power dissipations such that for many applications a heat sink is not required. 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. RoHS Compliant |
