EN5335QI
3A Voltage Mode Synchronous Buck PWM
DC-DC Converter with Integrated Inductor
3-Pin Programmable Output
Description
The EN5335QI is a Power System on a Chip
(PowerSoC). 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 as
few as three external components that include
small value input and output ceramic capacitors
and a soft-start capacitor.
The Enpirion solution 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.
All Enpirion products are RoHS compliant and
lead-free manufacturing environment compatible.
