EN5360
6A Voltage Mode Synchronous Buck PWM
DC-DC Converter
RoHS Compliant
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.
