UCC28780EVM-002 is a dedicated evaluation board for DC/DC and AC/DC (off-line) SMPS. It is specially designed to evaluate UCC28780 resonant-mode, PWM controller ICs. With advanced features, such as a reverse-polarity protection, FET VCC under-voltage lockout (UVLO), MOSFET ZVS, phase accurate dimming, soft-start, and line-load transients, this EVM can meet the requirements of a wide variety of switch mode power supply topologies. This makes it an ideal choice for a range of applications, from industrial and medical instrumentation to consumer electronics and solar energy systems.

The UCC28780EVM-002 has an advanced design which includes a controller IC, a noise-free EMI filter with high frequency reactive components and an over-current detection circuitry. The board further includes rate-sense resistors, power transistors and a heatsink. This makes it very easy to install and use, as all of the connections necessary for a typical SMPS have been wired in the board.

The board offers adjustable output voltage and current with a high precision analog voltage and current adjustment resistance. The input voltage can be either a DC voltage or an AC voltage with a range of 4.5V to 265V. It can also operate in a single-ended or a differential input modes. The board also offers a 6-bit digital control for the adjustable output voltage and current.

With its integrated EMI filter, the board provides excellent EMI protection and when operating on a single-ended input, it offers over 70dB attenuation at the switching frequency of 200kHz. The output voltage ripple is typically less than 10mV. This helps reduce the background noise in the system.

The board is designed with safety features to protect the system and the user from any over-voltage or over-current situations and also supports a comprehensive safety package including over-temperature protection.

The UCC28780EVM-002 board is ideal for evaluating UCC28780 resonant-mode, PWM controller ICs and makes it incredibly easy to install and use. With its advanced features, it can offer high performance and reliability for a wide range of applications. Its safety features also ensure that it is safe and reliable, making it a great choice for all your evaluation needs.
