Basic Working Principle of LT1617ES5-1#TRPBF

The basic working principle of the LT1617ES5-1#TRPBF DC/DC switching regulator is based on a buck topology. In this type of power conversion system, an inductor is placed between the input voltage and the output voltage. The voltage signal from the input side is applied to the input of the PDM (Primary dump switch) driver through the rectifier circuit. The PDM driver then controls the opening and closing of the switching transistor. When the PDM signal turns on, current is supplied from the input side to the inductor. After the PDM signal turns off, the current that was flowing through the inductor is continued to flow to the output, due to the inductive properties of the inductor. The output voltage is then regulated by varying the width of the PDM signal. The LT1617ES5-1#TRPBF offers user programmable current limitation, under voltage lockout (UVLO) circuitry and voltage mode inner-current loop for precise voltage control. It also features a 0.5V error flag output to monitor output voltage.
