The TEA1733/38 family of IC´s are low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. They operate in fixed frequency mode. To reduce ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope compensation is integrated for Continuous Conduction Mode (CCM) operation.
