The UCC25661x family is a high-frequency LLC controller implementing input-power proportional control (IPPC) scheme, along with enhanced light-load management and multiple protection features. IPPC widens the control range of the LLC converter and simplifies the design of wide input or output-voltage range applications such as LED drivers and battery chargers. IPPC works without a PFC for non-universal input applications.

The UCC25661x family has enhanced light-load management that improves the efficiency while minimizing audible noise. To minimize standby power, the UCC25661x family directly disables the PFC controller when operating in burst mode.

The automatic capacitive region avoidance scheme along with the adaptive soft start with reverse recovery avoidance scheme verifies that the device never works in a mode where there is a potential to damage the FETs. The automatic capacitive region avoidance scheme makes the controller appropriate for working with a prebiased load.

The UCC25661x family comes with robust protection to help users design a reliable power supply. The UCC25661x family has options supporting high-voltage start-up, X-capacitor (X-cap) discharge, OVP, and extended gain range (EGR). See details in the Device Comparison table.
