TB9364 - Low Power OFF-Line Switcher

Download the TB9364 datasheet PDF. This datasheet also covers the TB9364-Top variant, as both devices belong to the same low power off-line switcher family and are provided as variant models within a single manufacturer datasheet.

General Description

TB9364 incorporates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown onto a monolithic IC.

Key Features

  • Superior to Linear/RCC.
  • Accurate hysteretic thermal shutdown protection.
  • automatic recovery improves field reliability.
  • Universal input range allows worldwide operation.
  • Simple ON/OFF control, no loop compensation needed.
  • Eliminates bias winding.
  • simpler, lower cost transformer.
  • Very low component count.
  • higher reliability and single side printed circuit board.
  • Auto-restart reduces delivered power by 95%.
