Enpirion^® Power Datasheet
EN5367QI 6A PowerSoC
Highly Integrated Synchronous Buck
With Integrated Inductor
Description
The EN5367QI is a Power System on a Chip
(PowerSoC) DC to DC converter with an integrated
inductor, PWM controller, MOSFETs and
compensation to provide the smallest solution size in
a 5.5x10x3mm 54-pin QFN module. It offers high
efficiency, excellent line and load regulation over
temperature and up to the full 6A load range. The
EN5367QI is specifically designed to meet the
precise voltage and fast transient requirements of
high-performance, low-power processor, DSP, FPGA,
memory boards and system level applications in
distributed power architecture. The EN5367QI also
features switching frequency synchronization with an
external clock, programmable soft-start as well as
thermal shutdown, over-current and short circuit
protection. The device’s advanced circuit techniques,
ultra high switching frequency, and proprietary
integrated inductor technology deliver high-quality,
ultra compact, non-isolated DC-DC conversion.
The Altera Enpirion integrated inductor solution
significantly helps to reduce noise. The complete
power converter solution enhances productivity by
offering greatly simplified board design, layout and
manufacturing requirements. All Altera Enpirion
products are RoHS compliant and lead-free
manufacturing environment compatible.
