TEA1792ATS/1,115

Overview

The TEA1792ATS/1,115 is a specialized power management IC designed for synchronous rectification in secondary-side applications. It supports both high-side and low-side control modes within AC-DC converters. The device operates with an input voltage range of 8.5 V to 38 V and delivers a maximum output voltage of 12 V. It functions reliably across a temperature spectrum from -40 °C to +150 °C. Packaged in a TSOP-6 surface-mount format, this controller integrates features to minimize external component count while maintaining high system efficiency from no-load to full-load conditions.

Feature Summary

• Provides precise synchronous rectification suitable for both high-side and low-side control configurations
• Features a wide operating supply voltage range to accommodate various converter topologies
• Generates a high drive output voltage capable of driving MOSFETs to minimum on-resistance
• Utilizes Silicon-On-Insulator (SOI) process technology for robust performance

Applications

• Adapters
• Quasi-resonant flyback systems
• Non-continuous conduction mode (DCM) power supplies

Procurement Notes

Verify the specific suffix '1,115' against official NXP documentation to confirm tape-and-reel packaging specifications and lot traceability requirements. Ensure that the ordering part number matches the exact package variant and marking code defined in the current datasheet revision. Cross-reference the manufacturer's latest lifecycle status to confirm availability and recommended replacement strategies if the component is approaching end-of-life.

Selection Notes

Select this component for designs requiring efficient secondary-side rectification in flyback converters. The integrated driver eliminates the need for external bootstrap circuits in many configurations. Consider the SOI technology benefits for noise immunity and switching speed. Evaluate the thermal performance within the specified operating temperature range to ensure reliability under continuous load conditions.
