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. 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) TEA1506P; TEA1506AP; TEA1506T; TEA1506AT 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 GreenChip™II control ICs, the TEA1506 has no internal high voltage start-up source and needs to be started by means of an external bleeder resistor. 1 2 3 4 8 7 6 5 TEA1506P TEA1506AP et4U.com • Short winding protection • Overtemperature protection DataSheet4U.com DataShee • Undervoltage protection (foldback during overload) • Low and adjustable overcurrent protection trip level • Soft (re)start.

A high level of integration leads to a cost effective power supply with a low number of external components. (1) GreenChip is a trademark of Koninklijke Philips Electronics N.V. TEA1506P; TEA1506AP; TEA1506T; TEA1506AT The special built-in green functions allow the efficiency to be optimum at all power levels. This holds for quasi-resonant operation at high power levels, as well as fixed frequency operation with valley switching at medium power levels. At low power (standby) levels, the system operates at a reduced frequency and with valley detection. Highly efficient and reliable supplies can easily be designed using the GreenChip™II control IC.
