UCC25800-Q1 Ultra-Low EMI Transformer Driver

Texas Instruments UCC25800-Q1 Ultra-Low EMI Transformer Driver integrates the switching power stage, the control, and the protection circuits to simplify isolated bias supply designs. It allows the design to utilize a transformer with higher leakage inductance but much smaller parasitic primary-to-secondary capacitance. This low-capacitance transformer design enables an order-of-magnitude reduction in the common-mode current injection through the bias transformer. This makes the transformer driver an ideal solution for the isolated bias supply in various automotive applications to minimize the EMI noise caused by high-speed switching devices. The soft-switching feature further reduces the EMI noise.
