Application Field

RT7297CHZSP has a variety of applications. It can be used for DC-DC conversion, switching regulator, DC-AC inverter, battery charger, etc. It is well suited for On/Off control of power supplies and auxiliary power sources. This IC is also ideal for personal portable equipment, battery-powered systems, personal computer power management and various kinds of circuit protection applications.

Working Principle

RT7297CHZSP is a non-synchronous buck switching regulator with an integrated Sensitive Gate Technology (SG) controller that prevents any possibility of wrong operation due to gate-source ringing. It supports advanced gate drivers, which allows for a fast response time, and consumes less current than a conventional buck switch controller. The power switch is also capable of a wide range of input and output voltages and gives the user the flexibility to switch between multiple power modes. As a result, it offers high performance, cost-efficiency, and compact size for power management.

To operate the IC, a user sets the characteristics of the power switch (voltage and current) and the operating mode of the regulator, either Voltage Mode or Current Mode. The current mode gives higher transient response and offers good stability, while voltage mode offers a lower cost solution. The RT7297CHZSP can also operate with peak current limiting, internal lossless switching, and soft start protection to further ensure performance, efficiency and improve system reliability.

Once the regulator is configured and the power is applied, the current mode control loop produces an output voltage that is proportional to the current flowing through the power switch. The main feature of the RT7297CHZSP is its Sensitive Gate Technology (SG) controller. This advanced technology features low gate-source ringing, low power consumption and fast response time. Furthermore, it provides the user with a wide range of customizable features to ensure optimal performance and reliability.
