Enpirion, Inc. 

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.
