AC-DC converters are essential for the operation of large and complex electrical systems and devices. The TB65S24C is a member of this important class of devices, and has a variety of applications. This paper will discuss the working principle of the TB65S24C and its various fields of application.

The TB65S24C is a unipolar, isolated, 25 V, 65 W DC-DC converter. It is designed for embedded applications where the power requirement ranges from 0.5 W to 65 W. The power converter has a wide input voltage range, from 16 V to 36 V, with a 50 kHz switching frequency, allowing it to be used in both isolated (high-side) and non-isolated (low-side) configurations.

The working principle of the TB65S24C is based on the switching of an inductor current in order to control the output voltage. This is achieved by switching two power N-channel MOSFETs in a specific sequence. One MOSFET is responsible for transferring power to the output, while the other MOSFET performs the role of dissipating the inductor current. The MOSFETs are activated during different phases of the cycle, allowing for a smooth transfer of power from the input to the output.

The TB65S24C converter is ideal for applications with a range of output voltage requirements. By changing the values of the output filter components, the output voltage can be adjusted from 5 V to 25 V. This makes the converter suitable for a range of applications, such as the powering of gate drivers for power switches, motor control applications, and solenoid and actuator control.

The TB65S24C also offers a range of protections to ensure reliable operation. Over-temperature, input undervoltage, and output overvoltage protection are integrated to ensure the safe operation of the converter. Additionally, integrated power-on reset and short-circuit protection are provided for the output voltage.

The TB65S24C is an efficient and reliable converter, and is suitable for a variety of applications. It is ideal for the powering of gate drivers for power switches, motor control applications, and solenoid and actuator control. It offers a wide input voltage range and adjustable output range, providing flexibility for many applications. The integrated protections ensure reliable and safe operation. In summary, the TB65S24C is an ideal choice for applications requiring a 25 V, 65 W DC-DC converter.
