TNY264PN

The part number TNY264PN corresponds to an integrated offline switcher IC (Integrated Circuit) manufactured by Power Integrations. These ICs are commonly used in power supply applications to regulate and control the conversion of AC voltage from the mains power line to the desired DC voltage output.

Key Features:

• Integrated Switching Regulator: The TNY264PN integrates a high-voltage power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and control circuitry into a single chip, simplifying circuit design and reducing component count.

• Flyback Topology: It operates based on the flyback topology, which is commonly used in isolated power supply applications.

• Primary Side Regulation (PSR): The chip employs primary-side regulation, allowing for feedback control directly from the primary side of the transformer, eliminating the need for an optocoupler and secondary-side feedback components.

• Energy-Efficient Design: Power Integrations ICs are known for their high efficiency and low standby power consumption, contributing to energy-efficient power supplies.

• Frequency Modulation: The switching frequency of the IC is frequency-modulated (FM) to reduce electromagnetic interference (EMI) emissions and improve system reliability.

• Safety Features: The IC includes comprehensive safety features such as overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown protection to ensure safe operation under abnormal conditions.

• Wide Input Voltage Range: The IC is designed to operate over a wide input voltage range, typically spanning from 85V AC to 265V AC, making it suitable for universal input voltage applications.

• Package Type: The TNY264PN is typically available in a through-hole DIP (Dual Inline Package) package, allowing for easy mounting on printed circuit boards (PCBs).

Applications:

• AC-DC Power Supplies: The TNY264PN is commonly used in low-power AC-DC power supply applications such as adapters, chargers, LED drivers, and auxiliary power supplies.
• Home Appliances: It finds application in various home appliances such as TVs, set-top boxes, white goods, and consumer electronics.
• Industrial Equipment: Used in industrial equipment and instrumentation for providing regulated DC power from the mains supply.
• LED Lighting: Employed in LED lighting applications for driving LED drivers and controlling LED brightness.
• Telecommunication Equipment: Utilized in telecommunication equipment for powering routers, switches, and network devices.
