TDA8380A - Control circuit for switched mode power supplies

Description

The TDA8380A is an integrated circuit intended for use as a control circuit in low-cost switched mode power supplies for television, monitors and small industrial equipment.

The TDA8380A operates using duty factor regulation in the fixed frequency mode.

Features

  • A low-current initialization circuit (maximum 150 µA) which can be switched off.
  • A bandgap reference generator.
  • Circuitry for slow-start combined with an accurate setting of the maximum duty factor (Dmax).
  • Programmable low supply voltage protection with one default value.
  • High supply protection circuitry.
  • Error amplifier with a transfer characteristic generator (TCG).
  • Protection against open- and short-circuited feedback loop.
