LTC3892 is a versatile controller, widely used in automotive and industrial applications. The main advantages of this controller are the ability to reduce power losses by adjusting the gate voltage of switching MOSFETs and extremely low quiescent current—3.6 μA at shutdown. This is a high voltage family of co
