TEA2096T

GreenChip dual synchronous rectifier controller

Rev. 1 — 9 September 2022

Product data sheet

1 General description

The TEA2096T is a new synchronous rectifier (SR) controller IC for switched-mode

power supplies. It incorporates an adaptive gate drive method for maximum efficiency at

any load.

The TEA2096T is a dedicated controller IC for synchronous rectification on the

secondary side of resonant converters. It has two driver stages for driving the SR

MOSFETs, which rectify the outputs of the central tap secondary transformer windings.

The two gate driver stages have their own sensing inputs and operate independently.

The TEA2096T is optimized for efficient operation with very low-ohmic MOSFETs and

switching at high frequencies.

The TEA2096T 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

• Supply current in energy save operation of 80 μA

• Regulation level of −29 mV for driving low-ohmic MOSFETs

2.2 Application features

• Drain sense voltage to 200 V

• Wide supply voltage range from 4.5 V to 38 V

• Dual synchronous rectification for LLC resonant

• Supports 5 V operation with logic level SR MOSFETs

• Differential inputs for sensing the drain and source voltages of each SR MOSFET

• SO8 package

2.3 Control features

• SR control without minimum on-time

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

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

• Interlock function to prevent simultaneous conduction of the external MOSFETs

• Supports 1 MHz switching frequency
