TB6819AFG - Critical Conduction Mode (CRM) PFC Controller IC

Description

Output voltage feedback pin.

This is the input of the error amplifier (E-Amp), OVP-2 and FOD.

The PFC output voltage should be resistively divided down and applied to this pin.

Features

  • Operating voltage range: 10.0 to 25 V.
  • Startup voltage: 12.0 V (typ. ).
  • Maximum drive current: 1.0 A.
  • Variety of protection circuits.
  • DC Input overvoltage protection (OVP-1).
  • PFC Output overvoltage protection (OVP-2).
  • Under voltage lockout (UVLO).
  • Feedback-loop open detector (FOD).
  • Brown out protection (BOP).
  • Package: SOP8 SOP8-P-225-1.27 P-SOP8-0406-1.27-001 Weight: 0.1 g (typ. ) Block Diagram GND 6 MUL.
