TNY278PN IC – Power Integrations Off Line Switcher IC

Description

1. Off-Line Switcher IC: The TNY278PN is an integrated circuit designed for off-line power supplies, meaning it is used in devices that are directly connected to the mains power supply without the need for an intermediate transformer. Off-line switcher ICs are commonly used in various electronic devices and power supplies.

2. Power Integrations: TNY278PN is manufactured by Power Integrations, a well-known semiconductor company specializing in high-voltage integrated circuits for power conversion.

3. Primary-Side Regulation (PSR): Off-line switcher ICs often utilize primary-side regulation, where the control circuitry is located on the primary side of the transformer. This configuration simplifies the design and reduces component count.

4. Energy Efficient: ICs like TNY278PN are designed to be energy-efficient, helping to meet energy efficiency standards and regulations in electronic devices.

5. Multiple Protection Features: Off-line switcher ICs typically incorporate various protection features such as over-voltage protection, over-current protection, and thermal shutdown to ensure safe operation and protect the circuit from faults.
