TEA2093TS/1Z

产品概述

• 产品概述

  TEA2093TS is a GreenChip synchronous rectifier controller IC for switched mode power supplies. It includes an adaptive gate drive for maximum efficiency at any load. It is a dedicated controller IC for synchronous rectification on the secondary side of asymmetrical half-bridge flyback and standard 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. This can generate its own supply voltage for battery-charging applications with low output voltage or for applications with high-side rectification. Typical applications are chargers, adapters, asymmetrical half-bridge flyback power supplies, flyback power supplies with very low and/or variable output voltage.

  • Adaptive gate drive for maximum efficiency at any load
  • Operates in a wide output voltage range down to 0V
  • Self-supplying for operation with low output voltage
  • Operates with standard and logic level SR MOSFETs
  • TSOP6 package, adaptive gate drive for fast turn-off at the end of conduction
  • Undervoltage lockout (UVLO) with active gate pull-down
  • Typical supply current in no-load operation below 200μA
  • Supports USB BC, USB PD and quick charge applications
  • Drain sense pin capable of handling input voltages up to 120V
  • Fabricated in a silicon-on-insulator (SOI) process
