TEA1733CP - NXP

TEA1733CP GreenChip SMPS controller

The TEA1733CP is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It operates in fixed frequency mode. To reduce ElectroMagnetic Interference (EMI), frequency jitter has been implemented. Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1733CP includes OverPower Protection (OPP.
