TNY278PN 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
