EN5339QI

DataSheeT – enpirion® power solutions EN5339QI 3A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION The EN5339QI is an Intel® Enpirion® Power System on a Chip (PowerSoC) DC-DC converter. It integrates the inductor, MOSFET switches, small-signal circuits and compensation in an advanced 4mm x 6mm x 1.1mm 24-pin QFN package. The EN5339QI PowerSoC is designed specifically to meet the driving demand for higher power density by providing a fully integrated buck converter. It features high efficiency, excellent line and load regulation and guarantees the full 3A output current over temperature. The EN5339QI 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. 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.
