FEATURES
Distinctive features
Universal mains supply operation (70 to 276 V AC)
High level of integration, giving a very low external
component count.
APPLICATIONS
Besides typical application areas, i.e. adapters and
chargers, the device can be used in TV and monitor
supplies and all applications that demand an efficient and
cost-effective solution up to 250 W.
Green features
Valley or 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)
Cycle skipping mode at very low loads. Pi <300 mW at
no-load operation for a typical adapter application
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 (latched
in TEA1533P, safe restart in TEA1533AP)
Short winding protection
Undervoltage protection (foldback during overload)
Overtemperature protection (latched in TEA1533P, safe
restart in TEA1533AP)
Low and adjustable overcurrent protection trip level
Soft (re)start
Mains voltage-dependent operation enabling level.
