UCC28610EVM-474

The UCC28610EVM-474 is an evaluation board used in the DC/DC & AC/DC (Off-Line) SMPS. This evaluation board, which is a versatile tool for development and evaluation of DC/DC and AC/DC SMPS, is powered by a dedicated Texas Instruments’ UCC28610 controller IC.

The UCC28610EVM-474, which uses a 4 x 4 PC board to support the controller IC, allows for a point-of-load conversion of source power. As an evaluation board for evaluation and testing of offline SMPS, it allows for low-cost evaluation of the UCC28610 controller IC. The board allows designers to measure and evaluate the performance of the controller IC in the various configurations with an output current of up to 1.3A.

The working principle of the UCC28610EVM-474 is based on the hysteretic control technique. This control scheme exploits the principle of hysteresis to regulate the output voltage of the DC/DC or AC/DC converters. Hysteresis is a phenomenon in which a variable changes its state after a certain amount of time from the reference state and then, after a certain amount of time, it changes back to the original state. The UCC28610 controller IC, using the hysteretic control technique, generates pulses of variable widths for the switching element, allowing for a fast and accurate regulation of the output voltage. The output voltage of the converter can be adjusted through external resistors and capacitors.

The UCC28610EVM-474 is designed to provide a robust platform for the evaluation and development of DC/DC and AC/DC converters. It is designed to operate with a wide range of input and output voltages, allowing designers to easily test and evaluate the performance of the controller IC with different configurations. The board also supports several control modes, including pulse-width modulation, constant off-time, and burst mode control, allowing for an evaluation of different power design strategies.

The UCC28610EVM-474 also features two separate output channels, allowing for flexible control of multiple loads. The board also features low utilization of components, allowing for high efficiency operation. Furthermore, the board also features protection circuitry, such as a brown-out protection, short circuit protection, and over-temperature protection.

In summary, the UCC28610EVM-474 evaluation board is a versatile tool for evaluation and development of DC/DC and AC/DC (Off-Line) SMPS. This board exploits the hysteretic control technique using the UCC28610 controller IC, allowing designers to evaluate and test the performance of the controller IC with different configurations. The board also features several protection circuits, allowing for a reliable operation.
