DC1317A-F

The DC1317A-F Evaluation Boards form part of a range of off-line switching power supply solutions provided for evaluating the DC-DC and AC-DC buck-boost switching controllers of the Linear Technology Corporation. Evaluating and debugging switching supplies can be a complex and time-consuming task, and the DC1317A-F Evaluation Boards simplify the situation considerably with a well-designed package that includes all of the essential components for quickly setting up a test bench.
The DC1317A-F Evaluation Boards consist of a printed circuit board populated with components such as the switching controller, power components and support circuitry, a DC input source, output connectors, and an external power transformer. The transformer allows for various input and output voltages, as well as multiple output voltages. The switching controller used in the board implements the popular buck-boost topology, and can accommodate both DC input and AC input applications.
The main component of the DC1317A-F boards is the switching controller, which controls the power switching of the buck or boost section of the power supply. This controller contains all of the necessary features for regulating the output voltage, such as a wide input voltage range, programmable output voltage, and over current and over voltage protection. The switching controller implements a closed loop control system when the external clock is activated, which ensures that the output voltage is properly regulated regardless of the load conditions or changes in input voltages and line regulation.
The output stages use a combination of linear and switch mode power components such as MOSFETs, IGBTs, diodes, resistors, and capacitors. These components must be properly selected for the desired output voltages and load conditions. In addition, the printed circuit board also includes components for power sequencing, snubber networks, soft-start, current limit, overvoltage protection, and remote sensing.
The DC1317A-F Evaluation Boards are designed for a variety of applications, such as output voltage adjustment, power supply sequencing and control, voltage tracking, and power factor correction. They can also be used in a variety of output ranges, such as up to 25 volts and up to 100 watts. These boards are well suited for use in a variety of AC and DC power sources, including automotive systems, and also for use in industrial systems, such as motor control, welding, communication, lighting, and medical.
In conclusion, the DC1317A-F Evaluation Boards are an ideal solution for evaluating and debugging off-line buck-boost switching power supplies. Not only are they cost-effective and time saving, but they also offer the flexibility of a wide range of power input and output conditions. The boards provide the necessary components for quickly setting up a test bench, while the well-designed package includes components for voltage and current adjustment, power sequencing, snubber networks, soft-start, and overvoltage protection.
