TEA1792TS/1,115

Overview

The TEA1792TS/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 configurations within non-continuous conduction mode (DCM) and quasi-resonant flyback converters. The device operates on an input voltage range of 8.5 V to 38 V and features a maximum output voltage capability of 12 V. It functions reliably across a temperature range from -40 °C to +150 °C and is housed in a TSOP-6 surface-mount package.

Feature Summary

• Provides precise synchronous rectification functionality suitable for both high-side and low-side control architectures.
• Features a wide operating supply voltage range to accommodate various converter topologies.
• Delivers a high drive output voltage to effectively drive MOSFETs to their lowest possible on-resistance.
• Incorporates adjustable level shifting for the drive section to optimize performance.

Applications

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

Procurement Notes

Verify the specific suffix '1,115' against official NXP documentation to confirm exact packaging and reel specifications. Ensure compatibility with the TSOP-6 footprint during PCB layout. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve. Cross-reference the manufacturer part number with distributor listings to avoid confusion with similar series variants.

Selection Notes

Select this component for designs requiring integrated synchronous rectification control in DCM or quasi-resonant flyback converters. The wide input voltage range allows flexibility in transformer design. Consider the TSOP-6 package constraints for board space. Evaluate the need for high-side versus low-side control capabilities based on the specific circuit topology requirements.
