The TNY267PN is a 6.5W offline switcher IC, and its maximum output power depends on the input voltage, output voltage, and other design parameters. However, as a general guideline, it can handle up to 6.5W of output power with a suitable transformer and component selection.
To ensure the TNY267PN operates within its SOA, follow the guidelines in the datasheet for maximum drain-source voltage, drain current, and power dissipation. Also, ensure proper thermal management, such as using a suitable heat sink and layout, to keep the junction temperature within the recommended range.
The recommended transformer design for the TNY267PN involves selecting a transformer with a suitable turns ratio, core material, and winding configuration. Power Integrations provides a transformer design guide and examples in the datasheet and application notes. It's essential to follow these guidelines to ensure optimal performance and efficiency.
To optimize the TNY267PN for low standby power consumption, follow the guidelines in the datasheet for minimizing quiescent current. This includes selecting a suitable bias winding, optimizing the transformer design, and using low-power components. Additionally, consider using a low-standby-power mode, such as the 'burst mode' feature, to reduce power consumption during idle periods.
When designing an EMI filter for the TNY267PN, consider the following key factors: filter topology, component selection, and layout. Ensure the filter is designed to meet the relevant EMI standards, such as CISPR 22 and FCC Part 15. Follow the guidelines in the datasheet and application notes for EMI filter design and layout recommendations.
