Description
This Enpirion solution is a Power System on a
chip (PowerSoC). It is specifically designed to
meet the precise voltage and fast transient
requirements
performance, low-power processor, DSP, FPGA,
ASIC,
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
significantly helps in low noise system design
and productivity by offering greatly simplified
board
requirements.
All Enpirion products are RoHS compliant and
lead-free manufacturing environment compatible.
