TEA1733L - NXP

TEA1733L GreenChip SMPS control IC

The TEA1733 is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. The TEA1733 operates in fixed frequency mode. To reduce EMI, frequency jitter has been implemented. For Continuous Conduction Mode (CCM) operation, slope compensation is integrated. The controller can be set to accept an over-power situation for a limi.
