Product Overview
The TEA1723AT/N1 is a Switched Mode Power Supply (SMPS) Controller IC for power applications and operates directly from the rectified universal mains input. The device includes a high voltage power switch and has been optimized for fly-back 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 converter operates as a regulated voltage source from no-load up to the maximum output current and operates as current source that delivers the maximum current over a broad output voltage range. Using the TEA1723, a low power converter can be built at minimum cost and with the minimum number of external components. The controller regulates the output voltage with primary-side sensing which eliminates the need for an additional secondary feedback circuitry and simplifies the design.
- Primary sensing for control of output voltage without optocoupler and secondary feedback circuitry
- Minimizes audible noise in all operation modes
- Jitter function for reduced EMI
- Very low supply current in no-load condition with energy saver mode
- Incorporates high voltage start-up circuit with zero current consumption under switching operation
- Overvoltage protection on feedback control pin with auto-restart
- Undervoltage lock-out protection on IC supply pin
- Over temperature protection
- Soft-start by reduced peak current for zero and low output voltage
- Demagnetization protection for guaranteed discontinuous conduction mode operation
- Open and short-circuit protection of the feedback control pin
- Short-circuit protection of the charger output
- 700V High voltage power switch for global mains operation
12mW Enables no-load power consumption
