Very wide input range
Posted by: sbuttigieg

We are searching for an SMPS controller that can be used to produce a 24VDC output (non-isolated) from an input voltage range of 20Vac-265Vac?
I've scanned through your website but couldn't find any. Can you suggest a part number suitable for such an application?
Thanks

Pls go thrgh TNY 280PN,its an offline switch in Tiny switch family
Its input voltage range is 18VAC to 265VAC
How much is the load current requirement...??
pls see the datsheet of ths devise and chk wetthr it can support the power requirement

We do not have a device that can operate over such a wide range. Given the fact that the output can be higher than the input it would need to be buck-boost type.
Tinyswitch flyback design comes close but not gauranteed to start at such a low input voltage. With bias support Tinyswitch could be designed to sustain down to 20VAC but start-up could still be an issue. The other problem is output power. Depending on the output power you need the converter power switch is both high voltage and high current. This may require you to do a discrete design to solve problem.
