60V, 4A Monolithic Buck Regulator w/ Rail-to-Rail Programmable Output and Integrated Current Monitoring

November 28, 2016 // By Luc Desimpel

The LTC3649 step-down regulator combines key features of a high voltage buck regulator with a complete feature set that allows for ease of use in a variety of applications.  The output voltage can be programmed with one resistor from ISET to GND, or it can be programmed directly with a voltage on the ISET pin.  The LTC3649 accommodates a wide VIN and VOUT range of operation, and has the capability of monitoring and regulating on average output current as well as regulating on input voltage.
