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.
