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 Total Solution Footprint 14mm2 micro-QFN Package. Low VOUT Ripple for RF Compatibility Integrated magnetics enables a tiny solution High Efficiency, Up to 93% footprint, low output ripple, low part-count, and high Up to 600mA Continuous Output Current reliability, while maintaining high efficiency. The 5 MHz Switching Frequency complete solution can be implemented in as little as 2 14mm . 3 pin VID for Glitch Free Voltage Scaling VOUT Range 0.6V to VIN 0.25V The EP5358xUI uses a 3-pin VID to easily select the output voltage setting. Output voltage settings are Short Circuit and Over Current Protection available in 2 optimized ranges providing coverage UVLO and Thermal Protection for typical V settings. OUT IC Level Reliability in a PowerSOC Solution The VID pins can be changed on the fly for fast APPLICATIONS dynamic voltage scaling. EP5358LUI further has the Wireless and RF Applications option to use an external voltage divider. Wireless Broad Band Data Cards The EP5358xUI is a perfect solution for noise Small Form Factor Optical Modules sensitive and space constrained applications that require high efficiency.
