Power Integrations TNY285DG Environmental and export classification status description

The Power Integrations TNY285DG is a highly efficient off-line switcher IC (integrated circuit) that integrates a 700 V power MOSFET (metal-oxide-semiconductor field-effect transistor) with the control circuitry on a single chip. It is part of the TinySwitch-4 family of products designed for low-power AC-DC power supplies. Functions: 1. High Efficiency: Enables energy-efficient power supply designs. 2. Integrated MOSFET: Eliminates the need for an external MOSFET, reducing component count and board space. 3. Robust Protection Features: Over-temperature, over-voltage, and over-current protection for reliability. 4. Frequency Modulation (FM) Technology: Minimizes EMI emissions for compliance with regulatory standards. Applications: 1. Power Adapters: Used in mobile phone chargers, laptop adapters, and other consumer electronics. 2. LED Lighting: Suitable for LED driver applications where high-efficiency power conversion is essential. 3. Home Appliances: Can be used in white goods such as refrigerators, washing machines, and air conditioners. 4. Industrial Power Supplies: Ideal for low-power industrial applications. Alternative Components: 1. LinkSwitch-TN: Another IC from Power Integrations designed for non-isolated power supplies. 2. TOPSwitch: This product line from Power Integrations offers integrated switcher ICs for higher power applications. 3. Fairchild Semiconductor FSTM: An alternative option for off-line switcher ICs with integrated power MOSFETs. Embedded Modules: The Power Integrations TNY285DG does not have additional embedded modules. Related Q&A: 1. Q: What is the typical efficiency of the TNY285DG in a power adapter application? - A: The TNY285DG can deliver efficiency levels of up to 85% in power adapter applications, depending on the design and load conditions. 2. Q: How does the over-temperature protection feature in the TNY285DG work? - A: The over-temperature protection monitors the junction temperature of the IC and activates a shutdown mechanism if the temperature exceeds a safe threshold, preventing damage to the device. 3. Q: Can the TNY285DG be used in designs requiring power factor correction (PFC)? - A: The TNY285DG does not include power factor correction functionality. For PFC requirements, a separate controller or IC would need to be added to the design. 4. Q: What is the input voltage range supported by the TNY285DG for off-line power supplies? - A: The TNY285DG supports a wide input voltage range, typically from 85 VAC to 265 VAC, making it suitable for universal mains input applications. 5. Q: Is synchronization possible between multiple TNY285DG ICs in parallel operation for higher power applications? - A: The TNY285DG does not support synchronization features for parallel operation. For higher power requirements, a different solution with synchronization capabilities should be considered.
