1. General description
The GreenChip III is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1751(L)T (TEA1751T and TEA1751LT) combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components. The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches off to maintain high efficiency. During low power conditions, the flyback controller switches to frequency reduction mode and limits the peak current to 25 % of its maximum value. This will ensure high efficiency at low power and go
