DC/DC Conver ter
The BQ60120HEA30 BusQor
™
Exa series converter is a
next-generation, board-mountable, isolated, wide input, reg -
ulated, fixed switching frequency DC/DC converter that uses
synchronous rectification to achieve extremely high conver -
sion efficiency. The BusQor Exa series provides an isolated
step down voltage from 35-75V to 12V with tight output volt -
age regulation in a standard “half-brick” module and is avail -
able in open-frame and baseplated version. BusQor con -
verters are ideal for customers who need multiple outputs and
wish to use point of load converters to work with a 12V rail.

able output current for powering intermediate bus architech -
ture systems. RoHS 5/6 compliant (see page 12 ).
