The DC231A is a power supply evaluation board designed to evaluate the performance of off-line switcher power supply topologies ranging from AC-DC converters to DC-DC converters, electronic ballast, and LED controls. It is designed for medical, consumer, and industrial applications and includes evaluation of primary- and secondary-side power components, magnetic components, snubbers, power semiconductor switching control elements, protection and control, and power stage optimization.

The DC231A board is based on an industry standard flip-chip topology consisting of two sites for secondary-side components, one site for an AC-DC bridge rectifier, one site for the PFC boost stage, and one site for a DC-DC buck. The board simplifies the design process for a wide variety of applications, which makes it especially valuable for anyone wanting to speed up development time for their projects.

The DC231A evaluation board provides excellent efficiency and power performance, as it has a wide range of settings for input voltage, output voltage, nominal current and frequency, as well as many options for component selection for primary and secondary sides. The board also offers programmable switching frequencies, allowing for optimization of power components and power stages. It even has an integrated over-temperature protection feature to extend the life of any battery-operated device.

The DC231A board also includes many features to optimize performance, including soft start, cycle-by-cycle and frequency jittering to reduce EMI, and pulse-width modulated (PWM) controllers, which allow for very precise control of the output voltage and current. Additionally, the board provides on-board digital diagnostics to monitor board temperature, input/output voltage/current, and control parameters.

One of the biggest advantages of the DC231A evaluation board is that it is pre-programmable. It comes with a set of optimized default parameters, allowing designers to start testing and evaluating a power supply with minimal configuration. The board can easily be connected to external components such as capacitors, inductors, and power semiconductors to make modifications to a power supply design, allowing for flexible testing.

The DC231A is an ideal device for designers who wish to rapidly evaluate, refine, and develop a reliable power supply circuit. The board’s integrated resourceful components, intuitive user interface, and on-board, pre-programmable power management components provide the user with an efficient power supply evaluation tool that quickly enables the development of next-generation power supplies.
