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.
2000 Dec 05
Universal mains supply operation (70 to 276 V AC)
High level of integration, giving a very low external
component count.
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.
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.
