I have a circuit with a dc photovoltaic string of about 280 volts feeding into this. The circuit calls for a SM12 chip with I think 4 pins. I guessed it was a voltage regulator of some kind but all the googled datasheets give different devices and none seem to fit this .
Can anyone tell me what it would be and where I would get one?
Its marked Pin 1 is L, Pin 2 is N, Pin 3 is +12 v, Pin 4 is 0 v Just noticed in the notes he says " A small Chinese postage stamp sized 12v dc power supply provides power ." Could these two be the same thing .

A system on a chip is an integrated circuit that integrates all or most components of a computer or other electronic system. These components almost always include a central processing unit memory, input/output ports and secondary storage – all on a single substrate or microchip, the size of a coin.It must contain digital, analog, mixed-signal, and often radio frequency signal processing functions, otherwise it will only be considered as an "Application Processor". As they are integrated on a single substrate, SoCs consume much less power and take up much less area than multi-chip designs with equivalent functionality. Because of this, SoCs are very common in the mobile computing and edge computing markets.
Systems on Chip are in contrast to the common traditional motherboard-based PC architecture, which separates components based on function and connects them through a central interfacing circuit board.

Oh crikey one of those sites !
How on earth do I fix my errors if I can't edit?
The title should be SM12
