EN5319QI

DESCRIPTION 

The EN5319QI 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 EN5319QI 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 EN5319QI 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. 

All Enpirion products are RoHS compliant and leadfree manufacturing environment compatible.
