EN5336QI Product Overview


The EN5336QI is a high-performance, highly integrated step-down DC-DC converter from Intel's Enpirion® 5300 series. Utilizing "Power System on Silicon" technology, this device integrates the controller, power MOSFETs, inductor, and compensation components into a compact 44-pin QFN package. As a non-isolated Point-of-Load (PoL) converter, it is specifically designed to meet the precise voltage and fast transient requirements of high-performance, low-power processors, DSPs, FPGAs, ASICs, and memory boards. The EN5336QI offers exceptional integration for modern power designs.

The EN5336QI's core advantages lie in its high integration density and industry-leading power density. It supports a wide input voltage range of 2.375V to 6.6V, offers an adjustable output from 0.75V to 6V, and delivers up to 3A of continuous current. Its 5MHz ultra-high switching frequency enables the use of small ceramic capacitors and achieves a footprint one-third that of competing solutions. This industrial-grade device (-40°C to 85°C) comes in a 10mm x 7.5mm 44-QFN package. The EN5336QI delivers outstanding power density in a tiny footprint.

The Enpirion solution significantly simplifies board design, layout, and manufacturing requirements, reducing system design complexity and cost. The EN5336QI is ideal for space- and efficiency-critical distributed power architectures, widely used in communications, industrial controls, data centers, medical devices, and portable electronics. The EN5336QI is a trusted choice for engineers worldwide.
