EN5360

6A Voltage Mode Synchronous Buck PWM

DC-DC Converter

Description

This Enpirion EN5360 is a Power System on a Chip

DC-DC converter. It is specifically designed to meet

the precise voltage and fast transient requirements of

present and future high-performance, low-power

processor, DSP, FPGA, memory boards and system

level applications in a distributed power architecture.

Advanced circuit techniques, ultra high switching

frequency, and very advanced, high-density,

integrated circuit and proprietary inductor technology

deliver high-quality, ultra compact, non-isolated DC-

DC conversion. Operating this converter requires only

four external components that include small value

input and output ceramic capacitors and a soft-start

capacitor.

The Enpirion EN5360 significantly helps in system

design and productivity by offering greatly simplified

board design, layout and manufacturing requirements.

In addition, a reduction in the number of vendors

required for the complete power solution helps to

enable an overall system cost savings.
