Enpirion^® Power Datasheet
EN5365QI 6A PowerSoC
Voltage Mode Synchronous Buck PWM
DC-DC Converter with Integrated Inductor
3-Pin VID Output Voltage Select
Description
This Altera Enpirion solution is a Power System
on a Chip (PowerSoC). 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 very advanced, 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 three external
components that include small value input and
output ceramic capacitors and a soft-start
capacitor.
The Altera Enpirion integrated inductor solution
significantly helps in low noise system design
and productivity by offering greatly simplified
board design, layout and manufacturing
requirements.
All Altera Enpirion products are RoHS compliant
and lead-free manufacturing environment
compatible.
