EXB100 Series
Single output
•Ultra wide trim range, 60% to 110% (1.08 Vdc to 5.5 Vdc)
•High efficiency, 91.5% @ 5 Vdc, 90.5% @ 3.3 Vdc
•Basic insulation (input to output)
•Industry standard half-brick pin-out
•No minimum load
•Overvoltage and overtemperature protection
•Remote ON/OFF
•Available RoHS compliant
The EXB100 series of 100 W single output isolated dc-dc converters are specially
designed to meet the power needs of low voltage silicon. Housed in an open-frame
package with standard footprint, these latest generation converters offer efficiencies as
high as 91.5% (typical on 5 V at 20 A). The series comprises two 48 V input models
with 5 V and 3.3 V outputs. The 3.3 V model features a wide input range, trimmable
output voltage and 30 A output (the 5 V model is limited to 20 A). Remote sense and
remote ON/OFF facilities are included as standard, and the converters are
comprehensively protected against overcurrent, overvoltage and overtemperature
conditions.
