The Intel® Enpirion® EP5348UI 400 mA DC-DC step-down (buck) converter with integrated inductor delivers an optimal trade-off between footprint and efficiency. It is a perfect alternative to replace less efficient low-dropout regulators (LDOs) in space-constrained applications that require improved efficiency. The 0.9 mm profile and small footprint enable the use of this part where space is at a premium.
A complete power system-on-a-chip (PowerSoC), the EP5348UI integrates power switches, inductor, gate drive, controller, and compensation in a tiny 2.0 mm x 1.75 mm package, greatly simplifying the design process. In addition, this point-of-load solution only requires a few tiny external components, reducing the overall solution cost and simplifying the supply chain.
This product is an excellent choice for any application where poor LDO efficiency creates thermal and battery life challenges that could jeopardize meeting Energy Star requirements.
