It is used in AC/DC and DC/DC converters, industrial control systems, motor control systems, power modules such as flyback, resonant, PFC and LLC converters, non-isolated and isolated dc-dc converters, PFC+LLC converters, automotive systems and solar inverters.

Working Principle

The EL7155CS-T13 is a revolutionary PMIC - Gate Drivers; its working principle involves the use of a signal isolation bus and the power-sensing signal feedback. When the signal isolation bus is connected, the three-channel gate driver starts working. This signal isolation bus is used for transmitting the signals for power switching, such as MOSFET and IGBT driving. The power-sensing signal feedback is then used to control the power switch to turn on/off, or regulate the output power as required. The device also uses the optimized digital signal processing algorithm which provides the power output with higher efficiency. The EL7155CS-T13 also has built-in protections like over-temperature, over-voltage protection, short-circuit and over-current protection. The device also has a programmable soft-start feature which ensures the system difficulty in starting. The EL7155CS-T13 also provides programmable adjustment of the output current slew-rate and flexible programming of the startup delay time, so the product is capable of controlling different MOSFETs and bridge configurations.
