EN6360QA 8A PowerSoC
Highly Integrated Synchronous
DC-DC Buck with Integrated Inductor
Description
The EN6360QA is an 8A 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
an 8x11x3mm 68 pin QFN module. The EN6360QA 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 EN6360QA features switching
frequency synchronization with an external clock or
other EN6360QAs 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.
