Controller IC Chip - TEA1733SMD 1733 SOP-8 Chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP1111) 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 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 components. 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 combination of fixed frequency operation at high output power and frequency reduction at low output power provides high efficienc
