TEA2017ABT/2

Digital configurable LLC and DCM/QR PFC controller

Tamb = 25 °C; VSUPIC = 19.5 V; all voltages are measured with respect to GND; currents are positive when flowing into the

IC; unless otherwise specified.

Expected values for different MTP settings (min/typ/max) are provided in the documentation in the Ringo software.
