Description
The QSK033A0B series of dc-dc converters are a new generation of DC/DC power modules designed to support
12Vdc intermediate bus applications where multiple low voltages are subsequently generated using point of load
(POL) converters. The QSK033A0B series are enhanced from their predecessor QBK033A0B series, with
improvements to the internal shutdown control, improved response to input voltage transients, and inclusion of output
reverse current protection during startup. The QSK033A0B series operate from an input voltage range of 36 to 60Vdc
and provide up to 33A output current at 12V in an industry standard quarter brick. The converter incorporates
synchronous rectification technology and innovative packaging techniques to achieve efficiency reaching 94% 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.
