Noise resistant regulator

摘要

A converter for supplying a regulated voltage from an input to a load is disclosed. The converter supplies a regulated DC voltage from an input to a load using a power switch driven by a gate driver. It also includes a control loop for carrying a load condition signal and a control signal. The converter also includes a controller located on the control loop that generates the control signal based on the load signal. The controller is located on a first integrated circuit. The gate driver is located on a second integrated circuit. The load condition signal is encoded on the first integrated circuit and is decoded on the second integrated circuit.
