NXP Semiconductors TEA2096DB2201 Evaluation Board

NXP Semiconductors TEA2096DB2201 Evaluation Board has a TEA2096T SR controller and two 150V MOSFETs. The TEA2096T is a dedicated controller IC for synchronous rectification on the secondary side of resonant converters. It incorporates two stages for sensing and driving the SR MOSFETs. This rectifies the outputs of the central tap secondary transformer windings. The TEA2096T has a drain-source voltage rating of 200V. These features make the evaluation board suitable for applications with an output voltage of up to 60V.

Features

Dual synchronous rectification for resonant converters
Easy replacement of secondary-side rectifiers of an existing resonant converter
Differential inputs for sensing the drain and source voltages of each SR MOSFET independently
Adaptive gate drive for fast turn-off at the end of conduction and maximum efficiency at any load
Regulation level of −25mV for driving low-ohmic MOSFETs
SR control without minimum on-time

Supports 1MHz switching frequency
Interlock function to prevent simultaneous conduction of the external MOSFETs
Wide supply voltage range from 4.75V to 38V
Supports 5V supply operation with logic level SR MOSFETs
Supply current in energy save operation of 80μA
Undervoltage lockout (UVLO) protection with active gate pull-down
