Description

The EP5348UI delivers the optimal trade-off

between footprint and efficiency. It is a perfect

alternative to replace less efficient LDOs in space

constrained applications that require improved

efficiency.

The EP5348UI is a 400mA PowerSoC which

integrates

compensation, and the magnetics in a micro-

QFN Package. This highly integrated DCDC

solution offers up to 46-points better efficiency

than the comparable LDO.

reduction in power loss and improved thermals

are achieved. It enables extended battery life

and helps Meet Energy Star requirements.

Integrated magnetics enables a tiny solution

footprint, low output ripple, and high reliability,

while maintaining high efficiency. The complete

solution size is similar to an LDO and much

smaller than a comparable DCDC.
