DCM/QR/CCM & Multi Mode PFC + Resonant power supply control IC

The TEA2017AAT and TEA2017ABT are digitally configurable LLC and PFC combo controllers for high-efficiency resonant power supplies. The devices integrate LLC and PFC control functions, supporting low component-count power supply designs with configurable operating modes to optimize efficiency. Built on a configurable digital architecture with a high-speed hardware state machine, the TEA2017xxT family enables real-time control and flexible tuning of operating and protection parameters. Configuration settings can be secured to help protect proprietary designs. The TEA2017xxT also supports high efficiency at light loads through an LLC low-power mode, helping reduce power consumption across a wide operating range.
