EN6360QI
8A Synchronous Highly Integrated DC-DC
PowerSoC
Description
The EN6360QI 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 8x11x3mm 68 pin QFN module. It offers high
efficiency, excellent line and load regulation over
temperature and up to the full 8A load range. The
EN6360QI 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 EN6360QI
features switching frequency synchronization with an
external clock or other EN6360QIs 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 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 Enpirion products are RoHS
compliant and lead-free manufacturing environment
compatible.
