EN2340QI 4A PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor
DESCRIPTION
The EN2340QI is a Power System on a Chip
(PowerSoC) DC-DC converter. It integrates MOSFET
switches, small-signal control circuits, compensation
and an integrated inductor in an advanced
8x11x3mm QFN module. It offers high efficiency,
excellent line and load regulation over temperature
and up to the full 4A load range. The EN2340QI
operates over a wide input voltage range and is
specifically designed to meet the precise voltage and
fast transient requirements of high-performance
products. The EN2340QI features frequency
synchronization to an external clock, power OK
output voltage monitor, programmable soft-start
along with thermal and over current protection. The
device’s advanced circuit design, ultra high switching
frequency, integrated inductor technology delivers
high-quality, and non-isolated DC-DC conversion.
Intel Enpirion Power Solutions significantly help in
system design and productivity by offering greatly
simplified board design, layout and manufacturing
requirements. In addition, overall system level
reliability is improved given the small number of
components required with Intel Enpirion solution.
All Enpirion products are RoHS compliant, halogen
free and are compatible with lead-free manufacturing
environments.

NOTE A: NC pins are not to be electrically connected to each other or to any external signal, ground, or voltage. All pins
including NC pins must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage.
NOTE B: Shaded area highlights exposed metal below the package that is not to be mechanically or electrically connected
to the PCB. Refer to Figure 15 for details.
