Enpirion Power Datasheet EP5358LUI/HUI 600mA PowerSoC Voltage Mode Synchronous PWM Buck with Integrated Inductor Description Features The EP5358xUI (x = L or H) is rated for up to 600mA Integrated Inductor Technology of continuous output current. The EP5358xUI -40C to +85C Ambient Temperature Range integrates MOSFET switches, control, compensation, 2.5mm x 2.25mm x 1.1mm uQFN Package and the magnetics in an advanced 2.5mm x 2.25mm 2 micro-QFN Package. Total Solution Footprint 14mm Integrated magnetics enables a tiny solution footprint, Low V Ripple for RF Compatibility OUT low output ripple, low part-count, and high reliability, High Efficiency, Up to 93% while maintaining high efficiency. The complete 2 Up to 600mA Continuous Output Current solution can be implemented in as little as 14mm . 5 MHz Switching Frequency The EP5358xUI uses a 3-pin VID to easily select the output voltage setting. Output voltage settings are 3 pin VID for Glitch Free Voltage Scaling available in 2 optimized ranges providing coverage V Range 0.6V to V 0.25V OUT IN for typical V settings. OUT Short Circuit and Over Current Protection The VID pins can be changed on the fly for fast UVLO and Thermal Protection dynamic voltage scaling. EP5358LUI further has the option to use an external voltage divider. IC Level Reliability in a PowerSOC Solution The EP5358xUI is a perfect solution for noise Applications sensitive and space constrained applications that require high efficiency.
