The TEA1832TS/1X is a TDM current mode controller for flyback, forward or quasi-resonant converter. It is mainly used as an offline switching mode power supply (SMPS) for battery chargers, adapters, televisions and other consumer products relying on AC/DC power conversion. It supports an adjustable primary side feedback mechanism that provides improved power efficiency and better line/load regulation. It offers different protection features such as primary over-voltage protection (OVP), secondary over-current protection (OCP), and short circuit protection (SCP) making it suitable for various types of applications.

The TEA1832TS/1X can support primary side regulation (PSR) and active burst mode (ABM) technology, allowing for higher efficiency and power savings. The power supply design can be configured to operate in the forward, flyback or quasi-resonant converter operation. The TEA1832TS/1X is capable of controlling the output voltage and current with great accuracy.

The TEA1832TS/1X uses current-mode control to regulate outputs. It features a split-band control technique which allows it to maintain a constant operating frequency during active PFC bypass, thus improving power efficiency. The controller can control an integrated MBR switching element which ensures low power loss and easy loop compensation. The integrated PFC bypass employs the fast switching feature to minimize THD and improve PFC efficiency.

The TEA1832TS/1X also features an auxiliary winding control that enables it to maintain a constant switching frequency over a wide range of output current. This feature is especially useful in low-power applications. It also has a unique multi-fault protection circuit that allows the controller to detect and quickly respond to abnormal situations, such as a short circuit or an open loop. This helps protect the system from damage in case of a failure.

The TEA1832TS/1X can be configured in multiple operating modes, such as continuous conduction (CCM) and discontinuous conduction (DCM) modes. It is designed to provide high power and efficiency using a highly configurable control loop, providing excellent regulation and stability. The controller is also equipped with integrated digital dimming to facilitate the current ramping and smooth output transition during light load, improving the efficiency of the system. The TEA1832TS/1X also provides advanced diagnostics functions that allow the system to detect and respond to faults quickly and reliably.

The TEA1832TS/1X is an ideal solution for offline AC/DC power supplies. It provides excellent line and load regulation, high power efficiency, and reliable protection features. The controller also offers multiple operating modes, advanced diagnostic functions, and integrated digital dimming and PFC bypass, making it an excellent choice for any applications requiring a reliable, high power and efficient offline power conversion solution.
