TEA1791T/N1,118

The TEA1791T/N1,118 from NXP Semiconductors is a synchronous rectifier (SR) controller IC, part of the GreenChip family. It is engineered for the secondary side of discontinuous conduction mode and quasi-resonant flyback converters, enabling cost-effective power supply designs with a minimal number of external components.

This controller IC features accurate synchronous rectification functionality and a wide supply voltage range from 8.5 V to 38 V. It provides a high driver output voltage of 10 V, ensuring efficient driving of various MOSFET brands to their lowest RDS(on). The device also boasts low current consumption and contributes to high system efficiency across the load spectrum, from no load to full load.

Designed for applications such as adapters, the TEA1791T/N1,118 is suitable for any discontinuous conduction mode or quasi-resonant flyback system requiring a highly efficient and cost-effective solution. It is fabricated using a Silicon On Insulator (SOI) process and comes in an 8-lead SOIC package (SOT96-1) with surface mount mounting type.

Key features include undervoltage protection, ensuring reliable operation. The high level of integration simplifies design and reduces the overall component count.
