The TNY287KG is a 287W offline switcher IC, but the maximum output power depends on the specific application and design. Typically, it can handle up to 200W of output power with proper heat sinking and thermal management.
To ensure the TNY287KG operates within its SOA, follow the guidelines in the datasheet for voltage, current, and power dissipation. Also, make sure to provide adequate heat sinking, use a suitable transformer, and follow proper PCB layout and thermal design practices.
The recommended transformer design for the TNY287KG involves using a transformer with a turns ratio of 1:1.2 to 1:1.5, and a magnetizing inductance of at least 10uH. The transformer should also be designed to handle the maximum output power and voltage of the application.
To optimize the TNY287KG for low standby power consumption, use a high-value resistor (e.g., 1MΩ) between the BYPASS pin and the input voltage, and ensure that the input voltage is as low as possible while still meeting the application's requirements.
The BYPASS pin on the TNY287KG is used to connect a resistor to the input voltage, which helps to reduce standby power consumption by allowing the IC to enter a low-power mode when the output is not loaded.
