TEA1792TS/1Z

Overview

The TEA1792TS/1Z is a specialized power management IC designed for synchronous rectification in switch-mode 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 as a controller suitable for both high-side and low-side control applications, specifically targeting non-continuous conduction mode (DCM) and quasi-resonant flyback converters. Manufactured using silicon-on-insulator (SOI) technology, it integrates features to minimize external component count while maintaining high system efficiency across load ranges.

Feature Summary

• Provides precise synchronous rectification functionality optimized for secondary side control.
• Features a wide supply voltage range supporting flexible integration into various converter topologies.
• Delivers a high drive output voltage capable of driving MOSFETs to minimum on-resistance.
• Incorporates adjustable level shifting for the drive section to accommodate different gate drive requirements.

Applications

• Adapters
• Quasi-resonant flyback systems

Procurement Notes

Verify the specific suffix designation against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target switching frequency and thermal requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component for designs requiring integrated synchronous rectification control in DCM or QR flyback architectures. The SOI process offers robust performance characteristics. Evaluate the need for high-side versus low-side configuration based on the transformer winding arrangement. Confirm that the operating temperature range meets the environmental constraints of the end application.
