UCC25661x/UCC25661x-Q1 750KHz LLC Controllers

Texas Instruments UCC25661x/UCC25661x-Q1 750KHz LLC Controllers are high-frequency LLC controllers that implement an input-power proportional control (IPPC) scheme, enhanced light-load management, and multiple protection features. The IPPC scheme widens the control range of the LLC converter and simplifies the design of the output-voltage range and wide input applications, such as battery chargers and LED drivers. The device can even work without a PFC for non-universal input applications.
