... Figures 15 and 16 show examples of circuits for standby applications. They both provide two outputs: an isolated 5 V and primary referenced output. The first, using TNY266P, provides 10 W, and the second, using TNY267P output power. Both operate from an input range of 140 VDC to 375 VDC, corresponding to a 230 VAC or 100/115 VAC with doubler input ...
