TEA2208T/1J

TEA2208T Active bridge rectifier controller Rev. 1.4 14 April 2021 Product data sheet 1 General description The TEA2208T is the first product of a new generation of active bridge rectifier controllers replacing the traditional diode bridge. Using the TEA2208T with low-ohmic high-voltage external MOSFETs significantly improves the efficiency of the power converter as the typical rectifier diode-forward conduction losses are eliminated. Efficiency can improve up to about 1.4 % at 90 V (AC) mains voltage. The TEA2208T is designed in a silicon-on insulator (SOI) process. 2 Features and benefits 2.1 Efficiency features Forward conduction losses of the diode rectifier bridge are eliminated Very low IC power consumption (2 mW). 2.2 Application features Integrated high-voltage level shifters Directly drives all four rectifier MOSFETs Very low external part count Integrated X-capacitor discharge (2 mA) Self-supplying Full-wave drive improving total harmonic distortion (THD) S014 package 2.3 Control features Undervoltage lockout (UVLO) for high-side and low-side drivers Drain-source overvoltage protection for all external power MOSFETs Gate pull-down currents at start-up for all external power MOSFETsNXP Semiconductors TEA2208T Active bridge rectifier controller 3 Applications The TEA2208T is intended for power supplies with a boost-type power-factor controller as a first stage. The second stage can be a resonant controller, a flyback controller, or any other controller topology. It can be used in all power supplies requiring high efficiency: Adapters Power supplies for desktop PC and all-in-one PC Power supplies for television Power supplies for servers 4 Ordering information Table 1.Ordering information Type number Package Name Description Version TEA2208T/1 SO14 plastic small outline package 14 leads body width 3.9 mm SOT108-1 5 Marking Table 2.Marking Type number Marking code TEA2208T/1 TEA2208T TEA2208T All information provided in this document is subject to legal disclaimers.
