TEA1892ATS/1H

Power Supply Controllers, Monitors Overview

The TEA1892ATS/1H is a GreenChip synchronous rectifier controller IC designed for switched mode power supplies. It operates on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters, fabricated using Silicon-On-Insulator (SOI) process technology. The device features a wide supply voltage range from 8.5 V to 38 V and provides a high driver output voltage of 10 V to drive MOSFETs to their lowest R DSon. It includes selectable regulation levels for the driver stage and UnderVoltage Protection (UVP). The component is housed in a TSOP6 plastic surface-mounted package with six leads.
