General description
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 efciency at all power levels. This applies
to quasi-resonant operation at high power levels and quasi-resonant operation with valley
skipping.
The TEA1742T enables highly efcient and reliable supplies with power requirements of
up to 500 W, to be designed easily and with the minimum number of external components.

Features
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 Protection features
I Safe restart mode for system fault conditions
I Continuous mode protection by means of demagnetization detection (NXP patented)
I Accurate OverVoltage Protection (OVP)
I Open control loop protection
I IC OverTemperature Protection (OTP)
I Low and adjustable OverCurrent Protection (OCP) trip level
