EN5322QI Datasheet | Intel

- enpirion® power solutions EN5322QI 2A Power So C 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 pensation 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 pensation 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 ponents required for the plete power solution helps to enable an overall system cost saving. All Intel Enpirion products are Ro HS pliant and lead-free manufacturing environment patible.
