FEATURES
Distinctive features
•
Universal mains supply operation (70to 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
250W.
