The EN5322QI is a 2A PowerSoC high efficiency Synchronous Buck DC-DC Converter with integrated inductor, PWM controller, MOSFETS and compensation providing the smallest possible solution size. The 4MHz 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.
