UCC25800B-Q1 Overview
The 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 lowcapacitance transformer design enables an order of magnitude reduction in the mon-mode current...
