NXP Semiconductors TEA2096T Synchronous Rectifier Controller

NXP Semiconductors TEA2096T Synchronous Rectifier Controller is ideal for switched-mode power supplies. The TEA2096T incorporates an adaptive gate drive method for maximum efficiency at any load. The controller can be used 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.

Features

Efficiency features
- Adaptive gate drive for maximum efficiency at any load
- Supply current in energy save operation of 80μA
- Regulation level of −29mV for driving low-ohmic MOSFETs
Application features
- Drain sense voltage to 200V
- Wide supply voltage range from 4.5V to 38V
- Dual synchronous rectification for LLC resonant
