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, -40 ºC to +85 ºC
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
• 100 V, 100 ms input voltage transient rated
• Available RoHS compliant
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 100 W 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 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and is available with output voltages of
1.2 V, 1.5 V 1.8 V, 2.5 V, 3.3 V and 5.0 V. The output voltage is adjustable from 80% to 110% of
the nominal value. The series also has a remote ON/OFF capability. Overcurrent, overvoltage and
overtemperature protection features are included as standard. Full international safety approval
including EN60950-1 VDE and UL/cUL60950, reduces compliance costs and time to market.
