Working Principle of IXDE504D2T/R

The working principle of the IXDE504D2T/R is based on the half-bridge topology. A half-bridge is an electronic circuit consisting of two switches that together can power an electrical load. When the switches are turned on, they form a bridge of current between the load and the power supply. The circuit works by using a control signal to switch the switches on and off in a certain sequence, which results in the electrical load being powered. The switches can be controlled by either a 3.3V/5V logic input or an isolated analog input. In addition, the device offers adjustable dead times for additional safety and improved efficiency.
