DC-DC converters are widely used in today\'s power electronic applications due to their power conversion capabilities. The DHS100B12-T is a PFC converter with a power range from 50W to 100W, and is specifically designed for embedded Ultra Small Form Factor applications. It allows for high efficiency operation with ambient temperatures ranging from -40°C to +105°C. The DHS100B12-T is a true buck converter with a single-stage power topology, which can easily fit in various applications with tight space requirements.

The DHS100B12-T is a single-stage DC-DC converter, which means it applies active switch regulation. In active switches, power loss is minimal, resulting in high efficiency. The converter is driven by an external pulse width modulation (PWM) signal, allowing for a wide input voltage range and a precisely-regulated output voltage.

The DHS100B12-T is an ideal solution for applications that require a minimum noise level, such as industrial automation systems, point-of-load power supplies, internet of things devices, automotive audio systems, consumer electronic products, and medical products. Its high efficiency and switchable current limit protection can effectively reduce the system’s thermal management requirements. The DHS100B12-T converter also features an I/O isolation rating of up to 2.5kVdc for enhanced system reliability and safety.

The DHS100B12-T\'s high current output capability paired with its high efficiency makes it ideal for applications requiring a long operation life. Furthermore, its wide input voltage range of 10V-14V allows it to be used in a variety of applications. The converter achieves a high power level, enabling it to drive 100W of output power in a 9mm x 9mm package.

The working principle of the DHS100B12-T is simple. The device\'s internal PWM control circuit converts the input voltage to a pulse-width-modulated signal, which is applied to the main switch of the converter. The width of the applied pulse is proportional to the output voltage, and thus it regulates the output voltage. The device uses a dual current limit feature to limit the maximum load current while switching loads, ensuring that the maximum available output power is not exceeded.

Furthermore, the DHS100B12-T has over-current protection, under-voltage lockout, over-temperature protection, and soft-start for improved system reliability. In addition, the device has an output voltage that can be easily adjusted via an external resistor. This allows for maximum flexibility in setting the output voltage, as well as facilitating easy system design.

To summarize, the DHS100B12-T is an ideal DC-DC converter for applications requiring a true buck converter solution with a single stage power topology and small form factor. It is capable of providing high efficiency, high current output capabilities, and a wide input voltage range, while still maintaining high power levels. Furthermore, its rugged design ensures that it is reliable and safe in any operating environment.
