This is achieved through hard switching with synchronous rectification and discrete PWM control. The device works with high efficiency, up to 95%. Additionally, it features low RDS(on) and low quiescent current, as well as built-in protections from over-voltage, over temperature, over current and short circuit.The CUT75522 incorporates a synchronous buck controller with valley current mode control. It is based on a single high-side, low-side MOSFETs with integral driver, and the power is switched over a wide input voltage range. The device includes a valley current mode control with user adjustable peak current control. it also offers a wide range of features, including cycle-by-cycle current limit and short circuit protection, over temperature protection, active current sharing, power good signal, low voltage lock out and adjustable soft start.The CUT75522 is a simple and efficient solution for small scale/high power applications, allowing for low power loss. Its ability to handle high power output makes it particularly suitable for LED lighting and automotive applications. It is also suitable for power supplies such as charging circuits, converters, DC/DC adapters, and industrial power supplies.

Conclusion

CUT75522 is a versatile and efficient DC-DC converter with a wide input voltage range and high power output. It is well suited for a variety of applications, and its high efficiency and integrated protection features make it an optimal choice for demanding applications such as LED lighting and automotive applications.
