TEA1738FT: GreenChip SMPS control IC

The TEA1738FT is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in peak current and frequency control mode. Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1738FT IC includes OverPower Protection (OPP). This enables the controller to operate under overpower situations for a limited amount of time.
