Quarter-Brick Series

D u a l o u t p u t

DC/DC CONVERTERS

High Current, High Efficiency, Low Profile

NEW Product

• Two independent outputs

• High full load efficiency

• Wide ambient temperature range of -40 ºC to +85 ºC

• Up to 100% load imbalance

• Tracking, monotonic start-up

• Starts into pre-biased outputs

• Basic insulation system

• Over-voltage and over-temperature protection

• 100 V, 100 ms input voltage transient response

• Secondary side control, no optocouplers,

fast transient load response

• Available RoHS compliant

These are new high efficiency, open-frame, isolated 40 A converters in an industry standard dual

quarter-brick footprint. These converters deliver high output current at low voltages, and excel-

lent useable power density for today’s high end applications. This series features an input volt-

age range of 36 Vdc to 75 Vdc and output voltages of 1.2 V/3.3 V, 1.5 V/3.3 V, 1.8 V/3.3 V 2.5

V/3.3 V, and 5 V/3.3 V. The output voltage on each model is adjustable from 90% to 110% of

the nominal value. Typical efficiencies are 90%. This series also has a remote ON/OFF capabili-

ty. Over-current and over-voltage protection features are included as standard. Designed to

meet international safety agency approvals, including EN60950-1 and UL/cUL60950, this series

reduces compliance costs and time to market.
