TEA2095T/TE | Dual Synchronous Rectifier Controller

TEA2095T/TE | Dual Synchronous Rectifier Controller | NXP Semiconductors

The TEA2095T/TE is a high performance synchronous rectifier (SR) controller IC for switch mode power supplies.

This SR controller incorporates an adaptive gate drive method to save the maximum amount of energy at any load. To increase efficiency, the TEA2095T/TE can operate at 90μA with a -25 mV regulation level, which optimizes functionality for use with low-ohmic MOSFETs.

TEA2095T/TE’s undervoltage lockout (UVLO) protection allows devices to remain fully functional when supply voltage is below the minimum operating voltage and ensures the device stays off when voltage is below the UVLO threshold. This feature enhances overall system performance and increases efficiency.

Our product has two driver stages to drive SR MOSFETs, which rectify the outputs of the central tap secondary transformer windings. The two gate driver stages operate independently and come with differential inputs that sense the SR MOSFET’s drain and source voltages.

The TEA2095T/TE is optimally used in resonant power supplies for servers, PCs, TVs, adapters, and other switch mode power supplies.
