AC/DC offline switch, 85-265 VAC, 28W, DIP-8C-7

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

Product highlights:
Minimal system costs with increased flexibility
• Simple ON/OFF control, no loop compensation required.
• Selectable current limit through BP/M capacitor value
- Higher current limit extends peak power or, in open frame applications, maximum continuous power
- Lower current limit improves efficiency in enclosed adapters/chargers
- Allows optimal TinySwitch-III selection by replacing devices with no other circuit redesign
• Tight I²f parameter tolerance reduces system costs
- Maximises the power output of MOSFETs and magnets
- Minimises maximum overload power and reduces costs of transformer, primary terminal and secondary components
• ON-time extension - extends the control range/hold-up time at low cable lengths to reduce input bulk capacitance
• Self-biased: No bias winding or bias components
• Frequency jittering reduces EMI filter costs
• Pin-out simplifies heatsinking on the PCB
• SOURCE pins are electrically quiet for low EMI
