This converter can deliver up to 500 Watts of power over a wide operating temperature range of -40°C to +100°C. It also has a high efficiency of up to 90%, which helps to reduce power consumption and heat dissipation. The THM 10-1223 also has a wide input voltage range of 18-75V, making it suitable for use in a variety of different applications.

The THM 10-1223 is specifically designed for use in harsh environments. It has a wide environmental operating range of -40°C to +100°C, and a maximum relative humidity of 80%. It also features an input transient voltage surge protection of up to 600 VDC, protecting sensitive electronic circuits from power surges.

Working Principle

The THM 10-1223 is a synchronous buck converter, which produces an output voltage that is always lower than the input voltage. In this topology, the input voltage is converted into a fixed frequency AC current via a half-bridge switching circuit. The AC current is then converted back into a DC voltage by a synchronous rectifier, which is controlled by the converter\'s digital controller.

The digital controller of the THM 10-1223 controls the switching frequency and output voltage of the converter. The switching frequency is adjustable, allowing the user to optimize the efficiency of the converter for different applications. The digital controller also supports analog and digital programming of the output voltage, allowing for precise control of the output voltage. In addition, the converter features over-voltage, over-current and short-circuit protection, as well as maximum duty-cycle control.

The THM 10-1223 is a highly flexible and reliable solution for DC-DC power conversion. It is suitable for a wide range of applications, and its high efficiency makes it an efficient and cost-effective solution. The high voltage input range, wide environmental operating range and wide input transient voltage surge protection make it an ideal choice for applications in harsh environments.
