High Voltage Family of Controllers Reduces DC-to-DC Converter Cost and Size


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 — 3.6μA at shutdown. This is a high voltage family of controllers with an input/output voltage range of 4.5V to 60V. It’s very attractive for industrial customers because it can replace costly, bulky transformers in 48V input rail applications with less expensive, compact step-down converters.
