Eighth-Brick Series

Single output

DC/DC CONVERTERS High Current, High Efficiency, Low Profile
• Ultra-high efficiency topology
• Industry standard eighth brick footprint identical to quarter-brick pinout
• Low profile through-hole version
• Low profile with 38% space savings over other quarter-brick converters
• Wide ambient temperature range, -40ºC to +85ºC
• 80% to 110% output trim
• Monotonic start-up in normal and prebiased loads
• Basic insulation system
• Overvoltage and overtemperature protection
• Secondary side control, no optocouplers,
fast transient response
• 100V, 100ms input voltage transient rated

This is a new high efficiency, open-frame, low profile, single board, isolated DC/DC converter series in an industry standard eight-brick footprint that provides up to 100W of output power. The series delivers very high output current at low voltages, and excellent useable power for today’s high performance applications. The series features an input voltage range of 36 to 75VDC and is available with output voltages of 1.2V, 1.5V 1.8V, 2.5V, 3.3V and 5.0V. The output voltage is adjustable from 80% to 110% of the nominal value. The series also has a remote ON/OFF capability. Over-current, over-voltage and over-temperature protection features are included as standard. Full international safety approval including EN60950 VDE and UL/cUL60950, reduces compliance costs and time to market.

All specifications are typical at nominal input, full load at 25°C ambient unless otherwise stated
