EN5322QI 2A PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor
DESCRIPTION
The EN5322QI is a high efficiency synchronous buck
converter with integrated inductor, PWM controller,
MOSFETS, and compensation providing the smallest
possible solution size.
The 4 MHz operation 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.
Three VID output voltage select pins provide seven
pre-programmed output voltages along with an
option for external resistor divider. Output voltage
can be programmed on-the-fly to provide fast,
dynamic voltage scaling with smooth transitions
between VID programmed output voltages.
Intel Enpirion Power Solutions significantly help in
system design and productivity by offering greatly
simplified board design, layout and manufacturing
requirements. In addition, a reduction in the number
of components required for the complete power
solution helps to enable an overall system cost
saving.
All Intel Enpirion products are RoHS compliant and
lead-free manufacturing environment compatible.

PIN FUNCTIONS
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: White ‘dot’ on top left is pin 1 indicator on top of the device package.
