The TEA1999TK/2J from NXP Semiconductors is a synchronous rectifier (SR) controller IC belonging to the GreenChip family. It is specifically designed for the secondary side of flyback converters, driving the SR MOSFET to replace diodes for improved efficiency.
Key features include adaptive gate drive for optimal efficiency across various load conditions and a typical supply current below 250 µA in no-load operation. The device supports an output voltage range from 0 V to 21 V and its drain sense pin can handle input voltages up to 120 V. It is self-supplying for low output voltage applications and high-side rectification without an auxiliary winding.
This controller operates with standard and logic-level SR MOSFETs and supports charging applications like USB BC and QuickCharge. It is fabricated using a Silicon-On-Insulator (SOI) process and comes in an 8-HVSON package with surface mount mounting type.
The TEA1999TK/2J includes control features such as UnderVoltage LockOut (UVLO) with active gate pull-down, and a blanking input for varying switching frequencies. It is intended for use in high-efficiency power supplies such as chargers and adapters.
