EN5329QI 2A PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor
DESCRIPTION
FEATURES
The EN5329QI is an Intel® Enpirion® Power System on
a Chip (PowerSoC) DC-DC converter. The device
features an advance integrated inductor, integrated
MOSFETs, a PWM voltage-mode controller, and
internal compensation providing the smallest
possible solution size.
The EN5329QI is a member of the EN53x9QI family
of pin compatible and interchangeable devices. The
pin compatibility enables an easy to use scalable
family of products covering the load range from 1.5A
up to 3A in a low profile 4mm x 6mm x 1.1mm QFN
package.
The EN5329QI operates at high switching frequency
and allows for the use of tiny MLCC capacitors. It also
enables a very wide control loop bandwidth providing
excellent transient performance and reduced output
impedance. The internal compensation is designed
for unconditional stability across all operating
conditions.
Intel Enpirion integrated inductor solution
significantly helps to reduce noise. The complete
power converter solution enhances productivity by
offering greatly simplified board design, layout and
manufacturing requirements.

Figure 3: Pin Diagram (Top View)
NOTE A: NC pins are not to be electrically connected to each other or to any external signal, ground, or voltage. However,
they must be soldered to the PCB. Failure to follow this guideline may result in part malfunction or damage.
NOTE B: Grey area highlights exposed metal on the bottom of the package that is not to be mechanically or electrically
connected to the PCB. There should be no traces on PCB top layer under these keep out areas.
NOTE C: White ‘dot’ on top left is pin 1 indicator on top of the device package.
