DataSheeT enpirion power solutions EN5322QI 2A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN5322QI is a high efficiency synchronous buck Revolutionary Integrated Inductor converter with integrated inductor, PWM controller, Total Solution Footprint as Small as 50 mm2 MOSFETS, and compensation providing the smallest High Efficiency, up to 95 % possible solution size. Low Ripple Voltage 8 mVP-P Typical The 4 MHz operation allows for the use of tiny MLCC 2% Initial VOUT Accuracy with VID Codes capacitors. It also enables a very wide control loop 2.4 V to 5.5 V Input Voltage Range bandwidth providing excellent transient performance and reduced output impedance. The internal 2 A Continuous Output Current Capability compensation is designed for unconditional stability Low Dropout Operation: 100 % Duty Cycle across all operating conditions. Power OK Signal with 5 mA Sink Capability Three VID output voltage select pins provide seven Dynamic Voltage Scaling with VID Codes pre-programmed output voltages along with an 17 A Typical Shutdown Current option for external resistor divider. Output voltage can be programmed on-the-fly to provide fast, Under Voltage Lockout, Over Current, Short dynamic voltage scaling with smooth transitions Circuit, and Thermal Protection between VID programmed output voltages. RoHS Compliant MSL 3 260 C Reflow Intel Enpirion Power Solutions significantly help in APPLICATIONS system design and productivity by offering greatly Low Power Processors, Network Processors, simplified board design, layout and manufacturing DSPs FPGAs and ASICs requirements. In addition, a reduction in the number of components required for the complete power Replacement of LDOs solution helps to enable an overall system cost Noise Sensitive Applications such as A/V and RF saving. Computing, Computer Peripherals, Storage, All Intel Enpirion products are RoHS compliant and Networking, and Instrumentation lead-free manufacturing environment compatible.
