GreenChipTMII SMPS control IC
TEA1506P; TEA1506AP; TEA1506T; TEA1506AT
FEATURES
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.
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.
GENERAL DESCRIPTION
The GreenChipTM(1)II is the second generation of green Switched Mode Power Supply (SMPS) control ICs. A high level of integration leads to a cost effective power supply with a low number of external components.
The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates at a reduced frequency and with valley detection.
Highly efficient and reliable supplies can easily be designed using the GreenChipTMII control IC.
