TEA2093TS

GreenChip synchronous rectifier controller

Rev. 1 — 7 June 2022

Product data sheet

1 General description

The TEA2093TS is a member of a new generation of synchronous rectifier (SR)

controller ICs for switched mode power supplies. It includes an adaptive gate drive for

maximum efficiency at any load.

The TEA2093TS is a dedicated controller IC for synchronous rectification on the

secondary side of asymmetrical half-bridge flyback and standard flyback converters. It

incorporates the sensing stage and driver stage for driving the SR MOSFET, which is

rectifying the output of the secondary transformer winding.

The TEA2093TS can generate its own supply voltage for battery-charging applications

with low output voltage or for applications with high-side rectification.

The TEA2093TS is fabricated in a silicon-on-insulator (SOI) process.

2 Features and benefits

2.1 Efficiency features

• Adaptive gate drive for maximum efficiency at any load

• Typical supply current in no-load operation below 200 μA

2.2 Application features

• Operates in a wide output voltage range down to 0 V

• Drain sense pin capable of handling input voltages up to 120 V

• Self-supplying for operation with low output voltage

• Self-supplying for high-side rectification without the use of an auxiliary winding

• Operates with standard and logic level SR MOSFETs

• Supports USB BC, USB PD, and quick charge applications

• TSOP6 package

2.3 Control features

• Adaptive gate drive for fast turn-off at the end of conduction

• Undervoltage lockout (UVLO) with active gate pull-down
