资 源 简 介

The LTC®3127 is a wide VIN range, highly efficient, 1.35MHzfixed frequency buck-boost DC/DC converter that operatesfrom input voltages above, below or equal to the outputvoltage. The LTC3127 features programmable averageinput current limit, making it ideal for power-limited inputsources. The input current limit is programmed with asingle resistor and is accurate from 0.2A to 1A of average input current.The topology incorporated provides a conTInuoustransfer funcTIon through all operaTIng modes. Otherfeatures include <1μA shutdown current, pin-selectableBurst Mode operaTIon and thermal overload protection.The LTC3127 is housed in thermally enhanced 10-lead(3mm × 3mm × 0.75mm) DFN packages and 12-lead MSOP packages.
