NEW Product
• Ultra wide trim range, 60% to 110% (1.08V to 5.5V)
• High efficiency, 91.5% @ 5V, 90.5% @ 3.3V, 87.5% @ 1.8V
• Basic insulation (input to output)
• Industry standard half-brick pin-out
• No minimum load
• Over-voltage and over-temperature protection
• Remote ON/OFF
The EXB100 series of 100W 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 5V at 20A). The series comprises three 48V input models with
5V, 3.3V and 1.8V outputs. All models feature a wide input range, trimmable output
voltage and 30A output (5V is limited to 20A). Remote sense and remote ON/OFF
facilities are included as standard, and the converters are comprehensively protected
against over-current, over-voltage and over-temperature conditions.
