Eighth-Brick Series

S i n g l e o u t p u t

DC/DC CONVERTERS

High Current, High Efficiency, Low Profile

NEW Product

• 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.
