TEA1733 Datasheet | NXP Semiconductors

description 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 pensation is integrated. The controller can be set to accept an over-power situation for a limited amount of time. Two pins are reserved for protection purposes. Input under and over voltage protection, output over voltage protection and over temperature protection can be implemented with a minimal number of external ponents. At low power levels the primary peak current is set to 25% of the maximum peak current and the switching frequency is reduced to limit the switching losses. The bination of fixed frequency operation at high output power and frequency reduction at low output power provides high efficiency over the total load range. The TEA1733 enable low cost, highly efficient and reliable supplies for power...
