TEA1506T: GreenChip (tm) II SMPS control IC ARCHIVED

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.

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 GreenChip^TMII control ICs, the TEA1506 has no internal high voltage start-up source and needs to be started by means of an external bleeder resistor.
