AC/DC offline switch, 85-265 VAC, 15W, DIP-8B-7

TNY274-280 TinySwitch® family
Energy-efficient offline switcher with increased flexibility and extended power range

Product highlights
Lowest system costs with increased flexibility
• Simple ON/OFF control, no loop compensation required.
• Selectable current limit due to BP/M capacitor value
- Higher current limiting extends peak power or, in open frame applications, maximum continuous power
- Lower current limitation improves efficiency in closed adapters/chargers
- Allows optimal TinySwitch III selection by replacing devices without further circuit change
• Tight I2f parameter tolerance reduces system costs
- Maximizes the power output of MOSFETs and magnets
- Minimizes maximum overload performance and reduces transformer, primary terminal and secondary component costs
• ON-Time Extension - Extends the control range/hold time at low line lengths to reduce input ground capacitance
• Self-tensioning: No pre-tensioning winding or pre-tensioning components
• Frequency tremors reduce the cost of EMI filters
• Pin assignment simplifies the heat sink on the PCB
• SOURCE pins are electrically quiet for low EMI
