EP53F8QI
DataSheeT – enpirion® power solutions
EP53F8QI 1500mA PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor
DESCRIPTION
The EP53F8QI is an Intel® Enpirion® Power System on
a Chip (PowerSoC) DC-DC converter. The EP53F8QI
provides high efficiency in a very small footprint.
Featuring integrated inductor, MOSFET switches,
small-signal circuits and compensation in an
advanced 3mm x 3mm x 1.1mm 16-pin QFN package.
the device delivers up to 1500mA of continuous
output current. Total solution footprint can be as
little as 40mm2.
Output voltage is programmed via an external
resistor divider providing a wide range of flexibility
while maintaining a very small footprint.
Integration of the inductor reduces conducted and
radiated noise providing excellent compatibility with
sensitive RF and high speed data applications.

PIN FUNCTIONS
Figure 3. Pin Out 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.
