Philips Semiconductors
GreenChipII SMPS control IC
Product specification
TEA1506P; TEA1506AP;
TEA1506T; TEA1506AT
FEATURES
Distinctive features
Universal mains supply operation (70 to 276 V AC)
High level of integration; giving a low external
component count.
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.
APPLICATIONS
Besides typical application areas, i.e. TV and monitor
supplies, the device can be used in adapters and chargers
and all applications that demand an efficient and
cost-effective solution up to 150 W. Unlike the other
GreenChipII control ICs, the TEA1506 has no internal
high voltage start-up source and needs to be started by
means of an external bleeder resistor.
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 TEA1506; safe restart in TEA1506A)
Short winding protection
Undervoltage protection (foldback during overload)
Overtemperature protection
Low and adjustable overcurrent protection trip level
Soft (re)start.
