Description
The EBVW020A0B 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 EBVW020A0B series
operate from an input voltage range of 36 to 75Vdc, and provide up to 20A output current at output voltages from
6.0Vdc to 12.0Vdc, and 240W output power from output voltages of 12.1Vdc to 13.2Vdc in a DOSA standard eighth
brick. The converter incorporates digital control, synchronous rectification technology, and innovative packaging
techniques to achieve efficiency reaching 95.4% peak at 12Vdc output. This leads to lower power dissipations such
that for many applications a heat sink is not required. Standard features include on/off control, output overcurrent and
over voltage protection, over temperature protection, input under and over voltage lockout. Optional features include
output voltage remote sense and trim from 6.0Vdc to 13.2Vdc, passive droop paralleling, and base plate for heat sink
or cold wall applications.
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.
