DataSheeT enpirion power solutions EN5329QI 2A PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EN5329QI is an Intel Enpirion Power System on Integrated Inductor a Chip (PowerSoC) DC-DC converter. The device 2 Solution Footprint as Small as 50 mm features an advance integrated inductor, integrated Low Profile, 1.1mm MOSFETs, a PWM voltage-mode controller, and High Reliability Solution: 42,000 Years MTBF internal compensation providing the smallest High Efficiency, up to 95 % possible solution size. Low Output Ripple Voltage <5mV Typical P-P The EN5329QI is a member of the EN53x9QI family of pin compatible and interchangeable devices. The 2.4 V to 5.5 V Input Voltage Range pin compatibility enables an easy to use scalable 2A Continuous Output Current Capability family of products covering the load range from 1.5A Pin Compatible w/ EN5319 1.5A and EN5339 3A up to 3A in a low profile 4mm x 6mm x 1.1mm QFN Output Enable and Power OK Signal package. Under Voltage Lockout, Over Current, Short Circuit, The EN5329QI operates at high switching frequency and Thermal Protection and allows for the use of tiny MLCC capacitors. It also RoHS Compliant Halogen Free 260C Reflow enables a very wide control loop bandwidth providing excellent transient performance and reduced output APPLICATIONS impedance. The internal compensation is designed Applications with Low Profile Requirement such as for unconditional stability across all operating conditions. SSD and Embedded Computing SAN/NAS Accelerator Appliances Intel Enpirion integrated inductor solution significantly helps to reduce noise. The complete Controllers, Raid, Processors, Network Processors, power converter solution enhances productivity by DSPs FPGAs, and ASICs offering greatly simplified board design, layout and Noise Sensitive Applications manufacturing requirements. All Enpirion products are RoHS compliant and lead- free manufacturing environment compatible.
