In summary, the EN53x9QI is a footprint compatible PowerSoC synchronous buck converter family that integrates the inductor, digital controller, and power MOSFETs with multiple options. The EN5319QI offers 1.5 A, the EN5329QI offers 2 A, and the EN5339QI offers a full 3 A with no current derating. These parts come in a 4 mm x 6 mm x 1.1 mm package and only require 55 mm2 of total solution size (including external passives) which helps save board space. Design with an EN53x9QI PowerSoC is simple, requires minimal external components, and can help reduce the design cycle allowing the customer to get the system to market faster.
