TNY280PN ,Off-Line Switcher, 85-265 VAC, DIP-8C

The TNY280PN is part of the TinySwitch-III family, offering an energy-efficient, off-line switcher IC with an enhanced design for flexibility and extended power range. This device integrates a 700 V power MOSFET, oscillator, current limit (user selectable), and thermal shutdown circuitry, all in a compact DIP-8C package.

The IC supports simple ON/OFF control without needing loop compensation and offers selectable current limits, making it suitable for applications like chargers, adapters, and power supplies. Its advanced EcoSmart technology ensures extremely low power consumption during standby, meeting global energy efficiency regulations. It also provides enhanced safety with built-in thermal shutdown protection and adaptive switching cycle on-time extension.

Key Features :

• 700 V Power MOSFET integrated for high-voltage switching.
• Energy-efficient design with reduced standby power consumption.
• Selectable current limit via BP/M pin capacitor for flexible power adjustment.
• Pin-out simplifies heat dissipation and assembly with low EMI.
• Thermal shutdown with auto-restart enhances reliability and safety.
• 8-pin DIP package with 7 functional pins and 1 NC (not connected) for industry-standard compatibility.
