The Texas Instruments UCC28711EVM-160 evaluation module (EVM) helps designers evaluate the performance of the UCC28711 Constant-Voltage, Constant-Current PWM with Primary-Side Regulation. The 5W EVM is used for evaluating an off line adapter for USB applications. It converts a 90V to 265V RMS input voltage down to 5V DC, with a 1A current limit for USB adapter applications. It is intended for evaluation purposes and is not intended to be an end product.
