EN5312Q

EN5312Q 1 A Buck Regulator with Integrated Inductor Product Highlights Integrated Inductor 1 A continuous output current 2.4 V to 5.5 V input range Up to 95% peak efficiency Data Sheet   Excellent transient response, low ripple Requires two MLC filter capacitors (0805) 3-pin VID output voltage programming 4 mm x 5 mm x 1.1 mm QFN package   Fully RoHS compliant and Pb-free manufacturing line compatible Tiny Footprint Simple Layout, Easy Design Low Part Count Excellent Transient Response The Enpirion EN5312Q represents a revolution in low-power switching regulators.  The total solution footprint is 28 mm2, without compromising efficiency.  Requiring two external components, the EN5312Q makes regulator design a breeze. A complete power system on silicon (PSOS), the EN5312Q integrates power switches, Inductor, gate drive, controller, and loop compensation in a tiny 5 mm x 4 mm package.  The 1.1mm profile and small footprint enables the use of this part where space is at a premium. The EN5312Q utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels; or an external voltage divider can be employed to set the output voltage. This product is an excellent choice for low-power mobile applications such as smart-phone, personal media player or PDAs
