TNY278GN AC/DC offline switch, 85-265 VAC, 28W, SMD-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
