EXB100 Series
S i n g l e o u t p u t
NEW Product
• 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.
