The LTC3879IMSE#PBF switching voltage regulator manufactured by Analog Devices is a fast, wide operating range, no Rsense step-down controller. This component uses Burst Mode® operation to achieve high efficiency over a wide current range. It can operate with an input voltage between 4.4 V and 42 V, and has a maximum output current of 3 A. The LTC3879IMSE#PBF provides external compensation, adjustable soft-start and programmable output voltage. The internal MOSFET delivers 3 A of continuous load current. This component also has comprehensive protection features such as over-temperature, undervoltage lockout, input overvoltage and overcurrent protection. It is designed to minimize external parts count and simplify design. This component can be used in applications such as automotive, telecommunications, medical, industrial control and renewable energy.
