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 oopen-frame and baseplated version. BusQor con-
verters are ideal for customers who need multiple outtputs and
wish to use point of load converters to work with a 12V rail.
The BusQor Exa series convertters offer industry-leading use-
able output current for powering intermediate bus architech-
ture systems. RoHS 5/6 compliant (see page 12).
