DC-DC converters are devices that take energy from a single DC source, such as a battery, and convert it into a different DC voltage that can be used to power a broad range of applications. The THN 15-1213 is a high efficiency, single switch non-isolated DC-DC converter that is suitable for industrial, automotive and other high reliability applications.

The THN 15-1213 series is designed to operate from a wide DC source voltage of 8-32V or 12-60V. Depending on the input voltage, the output is adjustable from 0.6V to 13V, with maximum power up to 15W. It features an internal switch, optically isolated feedback, integrated over-temperature protection and soft-start function.

The working principle of the THN 15-1213 DC-DC converter is based on the Pulse Width Modulation (PWM) control technique. The duty cycle of the output voltage is determined by a special PWM control chip, which monitors and controls the output voltage. The control chip compares the output voltage against a reference voltage, and adjusts the Pulse Width to maintain an accurate output voltage.

The switching frequency of the control chip is adjustable from 200kHz to 500kHz. As the frequency increases, the EMI performance is improved. The internal switch is protected by current limit features and the switch is current-mode controlled, thus the response of the input voltage changes is very fast.

Due to its high efficiency up to 93%, the THN 15-1213 is capable of delivering high output power in temperature range from -40°C to +85°C without a heatsink. It also features a wide Range of EMI noise immunity for demanding industrial applications.

In conclusion, the main application of the THN 15-1213 DC-DC converter is to convert a single DC source voltage into a different DC output voltage for powering high reliability applications in industrial, automotive and other demanding environments. It is designed with high efficiency, low EMI noise, fast-response current-mode control and advanced protection features. The operating temperature range of -40°C to +85°C and wide input voltage range of 8-32V makes it suitable for high reliability applications.
