GENERAL DESCRIPTION
The GreenChipII 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.
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.
APPLICATIONS
Besides typical application areas, i.e. TV and Monitor supplies, the device
can be used in all applications that demand an efficient and cost-effective
solution up to 250 W.
