Additional preview pages of the TEA1742T datasheet.

The TEA1742T is a controller for Power Factor Correction (PFC).

Its high level of integration allows the design of a cost-effective power supply with a very low number of external components.

The special built-in green functions provide high efﬁciency at all power levels.

2.1 Distinctive features I Universal mains supply operation (70 V (AC) to 276 V (AC)) I Dual boost PFC with accurate output voltage (NXP patented) I High level of integration, resulting in a very low external component count and a cost-effective design I Low start-up supply voltage 2.2 Green features I Valley/zero voltage switching for minimum switching losses (NXP patented) I Frequency limitation to reduce switching losses I High ohmic resistive dividers possible to minimize losses 2.3 Protec.
