TEA2095T/1/S30J NXP

TEA2095T GreenChip dual synchronous rectifier controller Rev. 1.1 10 April 2020 Product data sheet 1 General description The TEA2095T is a new synchronous rectifier (SR) controller IC for switched-mode power supplies. It incorporates an adaptive gate drive method for maximum efficiency at any load. The TEA2095T is a dedicated controller IC for synchronous rectification on the secondary side of resonant converters. It has two driver stages for driving the SR MOSFETs, which rectify the outputs of the central tap secondary transformer windings. The two gate driver stages have their own sensing inputs and operate independently. The TEA2095T is optimized for efficient operation with very low-ohmic MOSFETs and switching at high frequencies. The TEA2095T 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 Supply current in energy save operation of 90 A Regulation level of 25 mV for driving low-ohmic MOSFETs 2.2 Application features Wide supply voltage range from 4.5 V to 38 V Dual synchronous rectification for LLC resonant Supports 5 V operation with logic level SR MOSFETs Differential inputs for sensing the drain and source voltages of each SR MOSFET SO8 package with exposed die pad Discharge of the output capacitor after mains disconnect 2.3 Control features SR control without minimum on-time Adaptive gate drive for fast turn-off at the end of conduction Undervoltage lockout (UVLO) protection with active gate pull-down Interlock function to prevent simultaneous conduction of the external MOSFETs Supports 1 MHz switching frequencyNXP Semiconductors TEA2095T GreenChip dual synchronous rectifier controller 3 Applications The TEA2095T is intended for resonant power supplies. In such applications, it can drive two external synchronous rectifier MOSFETs for the rectification of the voltages on the two secondary windings of the transformer. These MOSFETs replace diodes. 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 Bond-wire Version TEA2095T/1/S30 SO8 plastic small outline package 8 leads body width 3.9 mm Au SOT96-1 TEA2095T/1 SO8 plastic small outline package 8 leads body width 3.9 mm Cu SOT96-1 5 Marking Table 2.Marking Type number Marking code TEA2095T/1 TEA2095 TEA2095T All information provided in this document is subject to legal disclaimers.
