Eighth-Brick Series

Single output

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, -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
