Synchronous Buck PWM DC-DC
Converter with Integrated Inductor
3-Pin VID Output Voltage Select
Description
Features
The EN5395QI is a Power System on a Chip
(PowerSoC) 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, ASIC, memory boards, and system level
applications in a distributed power architecture.
Advanced circuit techniques, ultra high switching
frequency, and innovative, high-density,
integrated circuit and proprietary inductor
technology deliver high-quality, ultra compact,
non-isolated DC-DC conversion. Operating this
converter requires as few as five external
components that include small value input and
output ceramic capacitors and a soft-start
capacitor.
Altera’s Enpirion solution significantly helps in
system design and productivity by offering greatly
simplified board design, layout and
manufacturing requirements. In addition, a
reduction in the number of vendors required for
the complete power solution helps to enable an
overall system cost savings.
