DC to DC converters are an important part of a wide range of electronic devices and systems. They offer the ability to efficiently and reliably convert from one DC voltage to another, typically from a higher voltage source to a lower voltage utilization device or system. The THL 25-2423WI is a switch mode, DC to DC converter delivering up to 25 W output power. It is designed to provide up to 36 V output voltages from a wide input range of 9 to 36 VDC. This device is suitable for applications such as portable equipment, automotive or ATE (automatic test equipment).

The THL 25-2423WI has a variety of industry-standard features including a wide input/output voltage range, over-voltage protection, thermal shutdown, and current limit. With this device, the user can set the nominal output voltage to the desired level, between 0-36V. In addition, it has adjustable current limit protection and soft-start circuitry which can help to ensure reliable start-up. This device also offers a wide range of output voltages and current limits to ensure that the desired performance is achieved.

The THL 25-2423WI operating principle is based on a switch-mode topology, meaning that it converts an input voltage level to a much higher or lower voltage. As opposed to linear regulators, which simply dissipate the excess power, a switch-mode converter employs pulse-width modulation (PWM) to regulate the output power without generating too much heat. In a typical configuration, a voltage regulator is used in order to provide a constant output voltage. It has a buck topology, which allows it to generate an output voltage lower than its input voltage.

The control loop of the THL 25-2423WI consists of an optocoupler, pulse-width modulation controller, PWM comparator and power MOSFETs. The opto-coupler senses the output voltage and adjusts its output pulses in order for the switching frequency to compensate for any changes in the input voltage in order to maintain a steady output voltage. The voltage feedback signal from the opto-coupler is supplied to the PWM comparator by the PWM controller. Based on this signal, the PWM controller determines the width of the pulses and the MOSFETs switch these pulses on and off at a certain frequency, thus regulating the output voltage.

In addition to its basic voltage regulating functions, the THL 25-2423WI has additional features such as over-voltage protection and temperature shutdown. Over-voltage protection is critical to ensure the equipment does not exceed the voltages specified by the respective safety standards. Temperature shutdown is an additional safeguard which will shut down the device if the internal temperature exceeds a specified limit.

The THL 25-2423WI is a highly versatile and reliable DC to DC converter, well-suited for a wide range of applications such as tablets, medical devices, GPS receivers and many other systems and equipment that need to convert from a high-voltage source to a low voltage utilization device or system. It features both an adjustable output voltage and current limit, and safety features such as over-voltage protection and thermal shutdown to ensure complete and reliable protection.
