TEA2093TS/1Z

Power Supply Controllers, Monitors Overview

The TEA2093TS/1Z is a GreenChip synchronous rectifier controller IC designed for secondary-side rectification in asymmetric half-bridge and standard flyback converters. Manufactured using silicon-on-insulator (SOI) technology, it integrates sensing and driving stages to control SR MOSFETs. Key electrical parameters include a maximum drain voltage handling of 120 V, an operating supply current of 1.6 mA, and a quiescent current below 200 μA at no load. It supports output voltages down to 0 V and operates within a temperature range of -40 °C to +150 °C. The device is housed in a TSOP-6 package.

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix '1Z' against official NXP documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the TEA2093TS functional description. Confirm RoHS compliance status as indicated in the datasheet. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and sourcing channels.

Power Supply Controllers, Monitors Selection Notes

Select this controller for flyback topologies requiring secondary-side synchronization. It is suitable for designs needing self-supply in high-side configurations or low-voltage outputs. Consider the SOI process for robustness. Verify compatibility with the target SR MOSFET logic levels. Ensure the application falls within the specified 120 V drain voltage limit.

Power Supply Controllers, Monitors Part Context

The TEA2093TS belongs to NXP's GreenChip series of synchronous rectifier controllers. This family targets high-efficiency AC-DC conversion by replacing diodes with actively controlled MOSFETs on the secondary side. The TEA2093 specifically addresses non-isolated and isolated flyback applications, offering integrated solutions for sensing and driving to simplify design and improve overall converter performance.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct cross-reference availability from NXP. Evaluate alternative GreenChip SR controllers if pinout compatibility is required. Verify that substitute components support the same 120 V drain rating and SOI-based reliability standards for equivalent thermal and electrical performance.
