General description
The GreenChipTM(1)II is the second generation of green Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains. A level of integration leads to a cost effective power supply with a very 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.
The proprietary high voltage BCD800 process makes direct start-up possible from the rectified mains voltage in an effective and green way. A second low voltage BICMOS IC is used for accurate, high-speed protection functions and control.
Highly efficient and reliable supplies can easily be designed using the GreenChipII control IC.

Features
Distinctive features
- Universal mains supply operation (70 to 276 V AC)
- High level of integration, giving a very 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. Pi <300 mW at no-load operation for a typical adapter application
- On-chip start-up current source.
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 TEA1533P, safe restart in TEA1533AP)
- Short winding protection
- Undervoltage protection (foldback during overload)
- Overtemperature protection (latched in TEA1533P, safe restart in TEA1533AP)
- Low and adjustable overcurrent protection trip level
- Soft (re)start
- Mains voltage-dependent operation enabling level.
