Product Summary

The TEA1533T is a GreenChip II SMPS control IC. It is the second generation of green Switched Mode Power Supply (SMPS) control ICs operating directly from the rectified universal mains. A high level of integration leads to a cost effective power supply with a very low number of external components. Besides typical application areas, such as adapters and chargers, the TEA1533T can be used in TV and monitor supplies and all applications that demand an efficient and cost-effective solution up to 250W.

Parametrics

TEA1533T absolute maximum ratings: (1)VCC supply voltage: min=-0.4V, max=+20V; (2)VCTRL voltage on pin CTRL: min=-0.4V, max=+5V; (3)VDEM voltage on pin DEM: min=-0.4V; (4)Vsense voltage on pin Isense: min=-0.4V; (5)VDRAIN voltage on pin DRAIN: min=-0.4V, max=+650V; (6)Ptot total power dissipation: max=0.75W; (7)Tstg storage temperature: min=-55℃, max=+150℃; (8)Tj operating junction temperature: min=-20℃, max=+145℃.

Features

TEA1533T features: (1)Safe restart mode for system fault conditions; (2)Continuous mode protection by means of demagnetization detection (zero switch-on current); (3)Accurate and adjustable overvoltage protection; (4)Short winding protection; (5)Undervoltage protection (foldback during overload); (6)Overtemperature protection (latched in TEA1533T, safe restart in TEA1533AT); (7)Low and adjustable overcurrent protection trip level; (8)Soft (re)start; (9)Mains voltage-dependent operation enabling level.
