General description
The GreenChipÔII is the second generation of green Switched Mode Power Supply (SMPS) controller ICs operating directly from the rectified universal mains. A high 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 reduced frequency and with valley detection.
If burst mode operation is applied, the standby power level can even be reduced to below 1 W.
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, reliable supplies can easily be designed using the GreenChipÔII controller.
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/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)
- Burst mode operation for very low standby levels (<1 W)
- 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
- Short winding protection
- Undervoltage protection (foldback during overload)
- Overtemperature protection
- Low and adjustable overcurrent protection trip level
- Soft (re)start
- Mains voltage-dependent operation-enabling level.
