Product Summary

The TPS63060DSCR is a high input voltage buck-boost converter. The TPS63060DSCR provide a power supply solution for products powered by either three-cell up to six-cell alkaline, NiCd or NiMH battery, or a one-cell or dual-cell Li-Ion or Li-polymer battery. Output currents can go as high as 2A while using a dual-cell Li-Ion or Li-Polymer Battery, and discharge it down to 5V or lower. The buck-boost converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using synchronous rectification to obtain maximum efficiency. The applications of the TPS63060DSCR include Dual LI-Ion Application, DSC’s and Camcorders, Notebook Computer, Industrial Metering Equipment, Ultra Mobile PC’s and Mobile Internet Devices, Personal Medical Products, High Power LED’s.
