<p>Designers of today have an advanced array of tools at their disposal to develop next-generation, higher-performance, energy-efficient products. Whether needing to design a voltage regulator, an isolated dc-to-dc converter, or many other types of switching power supplies, the DC1174B-A evaluation board from ON Semiconductor is a powerful platform for the evaluation, debugging, and characterization of many of ON Semiconductor\'s advanced power management products.</p><p>The DC1174B-A board is a universal dc-to-dc converter evaluation board which works with many of ON Semiconductor\'s integrated dc-to-dc switching regulator solutions. It provides the necessary connections and support components to allow designers to quickly evaluate and prototype their designs. Designers can evaluate the performance of a wide range of switching power supplies, including buck, boost, and buck/boost converters, as well as LDO linear regulators.</p><p>The DC1174B-A is an intelligent, self-contained evaluation board whose printed circuit board includes a four-layer fra­mework. This framework includes a power layer on the bottom, a ground plane sandwiched between two signal layers, and a plane layer at the top which houses a microcontroller and other support components. The microcontroller communicates with external components through a user interface such as an LCD display, buttons, and a USB connection.</p><p>The board\'s power layer provides all of the necessary components to build the switching power supply. These components include flyback, forward, push-pull, full-bridge, and half-bridge controllers, as well as all of the necessary primary and secondary side inductors, transformers, capacitors, and resistors. This eliminates the need for designers to create a custom power board. The board\'s ground plane guarantees that all components remain safely connected and serves as a common return for all components. Finally, the user plane provides the support circuits to complete the design.</p><p>In terms of features, the DC1174B-A is highly configurable system with several switching topologies, voltage levels, and operating temperature ranges. Its internal or external sync input allows designers to synchronize to an external clock making the board ideal for applications such as telecom and server power supplies. Additionally, its adjustable current limit feature can be used to limit the output current and make the power supply more efficacious. Furthermore, the board\'s power board includes a multi-function bootstrap circuit that allows designers to vary the start-up speed of the power supply, as well as the size of the output capacitance.</p><p>In terms of operation, the DC1174B-A board provides two separate signals to control the power supply. The primary signal is derived from the DC1174B-A\'s power board and it is used to control the switching of the power supply. The secondary signal is generated by the user plane and it is used to adjust the output voltage and current limits. The combination of switching and secondary signals allows for precise control of the power supply.</p><p>In conclusion, ON Semiconductor\'s DC1174B-A evaluation board is a powerful platform for the evaluation, debugging, and characterization of many of ON Semiconductor\'s advanced power management solutions. It eliminates the need for designers to create a custom power board and provides a configurable system with several switching topologies, voltage levels, and operating temperature ranges. Additionally, its adjustable current limit feature can be used to limit the output current and make the power supply more efficacious. Whether needing to design a voltage regulator, an isolated dc-to-dc converter, or many other types of switching power supplies, the DC1174B-A board is the definitive tool.</p>
