Featured: NXP’s TEA2017 Digital Configurable LLC & Multimode PFC controller

All TEA2017xxT versions by NXP enable building a complete resonant power supply which is easy to design and has a very low component count.

The TEA2017xxT comes in a low profile and narrow body-width SO16 package. The TEA2017xxT digital architecture is based on a high-speed configurable hardware state machine ensuring very reliable real-time performance. During the power supply development, many operation and protection settings of the LLC and PFC controller can be adjusted by loading new settings into the device to meet specific application requirements. The configurations can be fully secured to prevent unauthorized copying of the proprietary TEA2017xxT configuration content.

In contrast to traditional resonant topologies, the TEA2017xxT shows a very high efficiency at low loads due to the LLC low-power mode. This mode operates in the power region between continuous switching (also called high-power mode) and burst mode.
