Description

This Enpirion solution is a Power System on

Silicon DC-DC converter. It is specifically

designed to meet the precise voltage and fast

transient requirements of present and future

high-performance, low-power processor, DSP,

FPGA,

applications in a distributed power architecture.

Advanced circuit techniques, ultra high switching

frequency, and very advanced, high-density,

integrated

technology deliver high-quality, ultra compact,

non-isolated DC-DC conversion. Operating this

converter requires as few as three external

components that include small value input and

output ceramic capacitors and a soft-start

capacitor.

The Enpirion solution significantly helps in

system design and productivity by offering greatly

simplified

manufacturing

reduction in the number of vendors required for

the complete power solution helps to enable an

overall system cost savings.

All Enpirion products are RoHS compliant and

lead-free manufacturing environment compatible.
