Description

The EN63A0QI is a Power System on a Chip

(PowerSoC) DC to DC converter with an integrated

inductor,

compensation to provide the smallest solution size in

an 10x11x3mm 76-pin QFN module. It offers high

efficiency, excellent line and load regulation over

temperature and up to the full 12A load range. The

EN63A0QI 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

features switching frequency synchronization with an

external clock or other EN63A0QIs for parallel

operation. Other features include precision enable

threshold,

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.
