TIDA-00940 is a 3-W, non-isolated bias power supply with up to 80% efficiency and excellent EMI performance, designed for motor control and drive subsystems in major appliances to save system costs, and other main benefits here. This reference design provides two non-isolated outputs with buck topology and is implemented using TI’s UCC28881 and TPS5405 controllers providing full protection. The hardware is designed and tested to pass EN-55014 Class B requirements for household appliances.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
