TEA1506T

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 GreenChipäII control ICs, the TEA1506 has no internal high voltage start-up source and needs to be started by means of an external bleeder resistor.

Notes
1. All voltages are measured with respect to ground; positive currents flow into the IC; pin VCC may not be current driven. The voltage ratings are valid provided other
ratings are not violated; current ratings are valid provided the maximum power rating is not violated.
2. Human Body Model (HBM): equivalent to discharging a 100 pF capacitor through a 1.5 k resistor.
3. Machine Model (MM): equivalent to discharging a 200 pF capacitor through a 0.75 H coil and a 10 resistor.

The GreenChipä(1)II TEA1506T is the second generation of green Switched Mode Power Supply (SMPS) control ICs. A high level of integration leads to a cost effective power supply with a low number of external components.

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 TEA1506T operates at a reduced frequency and with valley detection. Highly efficient and reliable supplies can easily be designed using the GreenChipäII control IC.
