EN6337QI
3A Voltage Mode Synchronous Buck PWM
DC-DC Converter with Integrated Inductor
Description
The EN6337QI is a Power System on a Chip
(PowerSoC) DC-DC converter. It integrates
MOSFET switches, small-signal circuits,
compensation, and the inductor in an advanced
4mm x 7mm QFN package.
The EN6337QI 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
distributed power architecture. 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 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.
