EN63A0QA 12A PowerSoC
Highly Integrated Synchronous Buck
With Integrated Inductor
Description
The EN63A0QA is a 12A 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 10x11x3mm 76-pin QFN module. The EN63A0QA
is AEC-Q100 qualified for automotive applications
and 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 EN63A0QA
features switching frequency synchronization with an
external clock or other EN63A0QAs for parallel
operation. Other features include precision enable
threshold, pre-bias monotonic start-up, and
programmable soft-start. 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.
