EN6362QI 6A PowerSoC
Highly Integrated Synchronous
DC-DC Buck with Integrated Inductor
Description
The EN6362QI 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
an 8x8x3mm 56 pin QFN module. It offers very high
efficiency and is able to provide 6A continuous output
current with no de-rating. The EN6362QI also
provides excellent line and load regulation over
temperature. The EN6362QI 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.
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
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.
