TDA8380A Overview
TDA8380A 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.
TDA8380A Key Features
- A low-current initialization circuit (maximum 150 µA) which can be switched off
- A bandgap reference generator
- Circuitry for slow-start bined 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
- An overload voltage foldback
- Primary current protection circuitry for both cycle-by-cycle and trip mode
- Protection against transformer saturation
