Single output
DC/DC CONVERTERS 16-30W High Efficiency DC/DC Converters
• High efficiency topology, 92% typical at 5V
• Industry standard footprint
• Wide operating temperature, -40˚C to +85˚C
(natural convection)
• 80% to 110% output trim
• No minimum load
• Overvoltage and overtemperature protection
• Remote sense compensation
• Remote on/off
The EXB30 is a new high efficiency open frame isolated 30 Watt converter series in an
industry standard footprint. The first five models in the series feature a 2:1 input voltage
range of 36 to 75VDC and are available in output voltages of 12V, 5V, 3.3V, 2.5V and 2V.
Each model is trimmable from 80 to 110% except the 12V output which has a wider
trim range of 60% to 110%. The sub 5V models have an output current rating of 8A.
Typical efficiencies for the models are 92% for the 5V, 90% for the 3.3V and 12V, 87%
for the 2.5V and 86% for the 2V version. The EXB30 series offers remote on/off and
remote sense compensation to correct for voltage drops at the load. Overcurrent,
overvoltage and overtemperature protection features are included as standard. With full
international safety approval including EN60950 and cUL1950, the EXB30 reduces
compliance costs and time to market.
All specifications are typical at nominal input, full load at 25°C unless otherwise stated
