EXB100 Series

Single output

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.
