DataSheeT enpirion power solutions EP5348UI 400mA PowerSoC Step-Down DC-DC Switching Converter with Integrated Inductor DESCRIPTION FEATURES The EP5348UI delivers the optimal trade-off between Integrated Inductor Technology footprint and efficiency. It is a perfect alternative to 400mA continuous output current replace less efficient LDOs in space constrained 2.0mm x 1.75mm x 0.9mm uQFN package applications that require improved efficiency. Small Solution Footprint The EP5348UI is a 400mA PowerSoC which Efficiency, up to 90% integrates MOSFET switches, control, compensation, V Range 0.6V to V V and the magnetics in a micro-QFN Package. This OUT IN DROP OUT highly integrated DC-DC solution offers up to 46- Short circuit and over current protection points better efficiency than the comparable LDO. A UVLO and thermal protection significant reduction in power loss and improved IC level reliability in a PowerSoC solution thermals are achieved. It enables extended battery life and helps Meet Energy Star requirements. APPLICATIONS Integrated magnetics enables a tiny solution Applications where poor LDO efficiency creates: footprint, low output ripple, and high reliability, while o Thermal challenges maintaining high efficiency. The complete solution o Battery Life challenges size is similar to an LDO and much smaller than a comparable DC-DC. o Failure to meet Energy Star requirements All Enpirion products are RoHS compliant and lead- Space-constrained applications free manufacturing environment compatible.
