EN5329QI

The Intel EN5329QI is a highly integrated Power System on a Chip (PowerSoC) DC-DC converter designed for applications requiring a small solution size and low profile. It features an advanced integrated inductor, MOSFETs, and a PWM voltage-mode controller with internal compensation, enabling a compact footprint as small as 50 mm2 and a low profile of 1.1mm.

This device operates within a 2.4V to 5.5V input voltage range and can deliver up to 2A of continuous output current. It achieves high efficiency, up to 95%, and provides excellent transient performance due to its wide control loop bandwidth. The integrated inductor solution also helps to significantly reduce noise, making it suitable for noise-sensitive applications.

The EN5329QI is pin-compatible with other devices in the EN53x9QI family, allowing for scalability from 1.5A to 3A. It includes features such as output enable, power OK signal, under-voltage lockout, over-current, short-circuit, and thermal protection. The converter operates at a high switching frequency, allowing the use of small MLCC capacitors.

Applications include SSDs, embedded computing, SAN/NAS accelerator appliances, controllers, processors, DSPs, FPGAs, and ASICs where low profile and high performance are critical. The simplified board design, layout, and manufacturing requirements enhance productivity.
