MAIN AND SATELLITE POWER STAMP

48V-to-PoL isolated DC-DC converters

The MAIN and SATELLITE Power Stamp are isolated DC-DC converters

that converts a 48V or 54V bus voltage into a low voltage suitable for

typical server’s motherboard subsystems.

Key Features and Benefits

• Over 94% efficiency at 1.8Vout

• Over 91% efficiency at 1.0Vout

• Up to 140W continuous output power / 200W peak

• Up to 70A continuous output current / 100A peak

• Wide 40V to 60V input voltage range

• Power density exceeding 300W/in3

• Parallelable with automatic phase shedding

• Flat efficiency curve over wide load ranges

• Source and sink mode for fast transient response

• Isolated power train

• Secondary side fully digital control
