TEA1792ATS/1Z

Overview

The TEA1792ATS/1Z is a synchronous rectification controller designed for high-side and low-side control in AC-DC power supplies. It operates within an input voltage range of 8.5 V to 38 V and supports a maximum output voltage of 12 V. The device functions optimally in discontinuous conduction mode (DCM) and quasi-resonant flyback systems, ensuring high system efficiency from no-load to full-load conditions.

Feature Summary

• Provides precise synchronous rectification functionality suitable for secondary side control.
• Features a wide supply voltage range to accommodate various converter topologies.
• Integrates high drive output capability to minimize MOSFET on-resistance.
• Utilizes Silicon-On-Insulator (SOI) technology for robust performance.

Applications

• Power adapters
• Quasi-resonant flyback converters
• Discontinuous conduction mode (DCM) systems

Procurement Notes

Verify the specific suffix 'ATS' against official NXP documentation to confirm pinout and electrical characteristics, as variations may exist within the TEA1792 family. Ensure compatibility with the intended switching frequency and transformer design parameters before integration into the final power supply architecture.

Selection Notes

Select this component for designs requiring efficient secondary-side rectification in DCM or QR flyback applications. The integrated driver reduces external component count, simplifying the PCB layout. Consider the operating temperature range and package type when evaluating thermal management requirements for the target enclosure.
