The TEA1721AT/N1 is a HV start-up flyback Controller with integrated MOSFET for 5W applications. It operates directly from the rectified universal mains input. The device includes a high voltage power switch (700V) and has been optimized for flyback converter topologies to provide High efficiency over the entire load range with ultra-low power consumption in the no-load condition. It provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The Burst mode frequency of 430Hz enables no-load power consumption below <10mW at high mains input.
● Low power SMPS controller for applications up to 5W
● Primary sensing without optocoupler and secondary feedback circuitry
● Minimizes audible noise in all operation modes
● Jitter function for reduced EMI
● Enables no-load power consumption
● Very low supply current in no-load condition with energy saver mode
● High voltage start-up circuit with zero current consumption during switching
● Over-temperature protection
