Evaluation and Demonstration Boards and Kits are essential tools used to facilitate the evaluation and validation of a designer\'s product concept. The DC1562B-H is a power supply evaluation board designed to evaluate highly efficient power supplies and is perfect for products that require high power and long run-time. The DC1562B-H provides a platform for the design and testing of 10V to 32Vdc DC-DC non-isolated switching regulators.

The DC1562B-H has multiple control features which makes it ideal for applications such as blade servers, power supplies, storage systems, and industrial automation. The board includes a UCC28730 control IC, four N-Channel FETs, two power inductors, two output capacitors, and six mounting slots. The DC1562B-H provides an adjustable current limit of up to 0.5A, an adjustable voltage rating of 10V to 32Vdc, and a switching frequency of up to 500 KHz.

The board is designed to simulate the power path of a real-world application with its on-board components, enabling designers to quickly develop and test their designs. An integrated digital interface enables users to modify various parameters like frequency, current limit and voltage. It also has an integrated microcontroller, allowing for custom code execution for parameters such as voltage corrections.

The DC1562B-H’s working principle is based on the basics of a switching regulator. It consists of an inductor, a capacitor, a diode, and a switch. When the switch is on, current flows through the inductor and the diode, and the capacitor stores energy. When the switch is off, the diode conducts current to the output load, and the current stored in the inductor is released slowly into the load.

In a switching regulator, the switch is the main component that determines the output voltage. The voltage output is determined by the duty cycle of the switch, which is the ratio of on-time to off-time. The on-time is set by the feedback voltage from the output, and is used to adjust the output voltage. The DC1562B-H uses this principle to provide its adjustable 10 to 32Vdc voltage.

The DC1562B-H also uses a control IC, which adjusts the duty cycle using feedback from the output voltage. A DAC is used to set the desired output voltage, and the feedback voltage is compared with the DAC voltage to set the duty cycle. The duty cycle determines the output voltage, and the feedback loop ensures that the output voltage is stable.

Overall, the DC1562B-H is a highly versatile power supply evaluation board designed for applications that require high power and long run-time. Its adjustable current limit and voltage range, as well as its integrated digital interface and microcontroller, provide a convenient platform to develop and test a designer’s next power supply design. With its working principle based on the basics of a switching regulator, the DC1562B-H provides a reliable source of power to ensure a successful product launch.
