Distinctive features
- Universal mains supply operation (70 to 276 V AC)
- High level of integration; giving a low external component count.
Green features
- Valley or zero voltage switching for minimum switching losses
- Efficient quasi-resonant operation at high power levels
- Frequency reduction at low power standby for improved system efficiency (≤3 W)
- Cycle skipping mode at very low loads.
Protection features
- Safe restart mode for system fault conditions
- Continuous mode protection by means of demagnetization detection (zero switch-on current)
- Accurate and adjustable overvoltage protection (latched in TEA1506; safe restart in TEA1506A)
- Short winding protection
- Undervoltage protection (foldback during overload)
- Overtemperature protection
- Low and adjustable overcurrent protection trip level
- Soft (re)start.
Target Applications
Besides typical application areas, i.e. TV and monitor supplies, the device can be used in
adapters and chargers and all applications that demand an efficient and cost-effective
solution up to 150 W. Unlike the other GreenChipTMII control ICs, the TEA1506 has
no internal high voltage start-up source and needs to be started by means of an external
bleeder resistor.
