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 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
