TEA1998TS GreenChip synchronous rectifier controller Rev. 1 16 February 2017 Product data sheet COMPANY PUBLIC 1 General description The TEA1998TS is a member of a new generation of Synchronous Rectifier (SR) controller ICs for switched mode power supplies with adaptive gate drive for maximum efficiency at any load. The TEA1998TS is a dedicated controller IC for synchronous rectification on the secondary side of flyback converters. It incorporates the sensing stage and driver stage for driving the SR MOSFET, which is rectifying the output of the secondary transformer winding. The TEA1998TS can generate its own supply voltage for battery charging applications with low output voltage or for applications with high-side rectification. The TEA1998TS 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 Typical supply current in no-load operation below 250 A 2.2 Application features Operates in an output voltage range between 10 V and 0 V Drain sense pin capable of handling input voltages up to 60 V Self-supplying for operation with low output voltage Self-supplying for high-side rectification without the use of an auxiliary winding Operates with standard and logic level SR MOSFETs Supports USB BC, QuickCharge and smart charging applications TSOP6 package 2.3 Control features Adaptive gate drive for fast turn-off at the end of conduction UnderVoltage LockOut (UVLO) with active gate pull-downNXP Semiconductors TEA1998TS GreenChip synchronous rectifier controller 3 Applications The TEA1998TS is intended for flyback power supplies. In such applications, it can drive the external synchronous rectifier MOSFET, which replaces the diode for the rectification of the voltage on the secondary winding of the transformer. It can be used in all power supplies that require a high efficiency, like: Chargers Adapters Flyback power supplies with very low and/or variable output voltage 4 Ordering information Table 1.
