The UCC25661x-Q1 family is a high-frequency LLC controller implementing input-power proportional control (IPPC) scheme, along with an enhanced light-load management and multiple protection features.

IPPC widens the control range of the LLC converter and simplifies the design of wide input applications such as high voltage to low voltage (HV-LV) redundant auxiliary, key-off, or bias isolated power supplies. IPPC also simplifies the design of wide output applications such as light electric vehicle battery chargers (scooters, mopeds, golf carts, and fork lifts).

The UCC25661x-Q1 family has enhanced light-load management that improves the efficiency while minimizing audible noise. To minimize standby power in charger applications, the UCC25661x-Q1 family can directly disable 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 ensures that the device can never work in a mode where there is a potential to damage the FETs. This scheme makes the controller ideal for working with a pre-biased load.

The UCC25661x-Q1 family comes with robust protection to help you design a reliable power supply. The UCC25661x-Q1 family has options supporting high-voltage startup (HVSU) and extended gain range (EGR). See details in the Device Comparison Table.
