TEA1999TS USB BC1.2 Synchronous Rectifier Controller for Flyback







Efficiency features

  • Adaptive gate drive for maximum efficiency at any load
  • Typical supply current in no-load operation below 250 µA

Application features

  • Operates in an output voltage range between 26 V and 0 V
  • Drain sense pin capable of handling input voltages up to 120 V
  • Self-supplying for operation with a 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, Quick Charge, and smart charging applications
  • TSOP6 package

Control features

  • Adaptive gate drive for fast turn-off at the end of the conduction
  • UnderVoltage LockOut (UVLO) with active gate pull-down
  • Blanking input for low and high switching frequency
  • Enable input for CCM operation and for disabling at start-up or shorted output
