KA1H0380RB - Fairchild Power Switch(FPS)

Download the KA1H0380RB datasheet PDF. This datasheet also covers the KA1L0380B variant, as both devices belong to the same fairchild power switch(fps) family and are provided as variant models within a single manufacturer datasheet.

Description

The SPS product family is specially designed for an off-line SMPS with minimal external components.

The SPS consist of high voltage power SenseFET and current mode PWM controller IC.

Features

  • Precision fixed operating frequency.
  • KA1L0380B/KA1L0380RB (50KHz).
  • KA1M0380RB (67KHz).
  • KA1H0380RB (100KHz).
  • Pulse by pulse over current limiting.
  • Over load protection.
  • Over voltage protection (Min. 23V).
  • Internal thermal shutdown function.
  • Under voltage lockout.
  • Internal high voltage sense FET.
  • Auto restart (KA1L0380RB/KA1M0380RB/KA1H0380RB).
