pcwortex said:using transformer (220 AC to 9 AC)+diode brigde+electrolytic capacitor+liner legulator(L7805)
Or need scheme?m?
Or make with IR213 buck converter
pcwortex said:hmmmm, but using similar chipset, which contains ac to dc regulators, you give least current. it is about 100 mA. maybe, you want to use this shipset to led.

is it too new or obsolete part ???

I do not know if its obsolete but still there are lots of distributors of the said component. I also emailed MAXIM's sales dept to inquire regarding the component's availability.
Anyway, if you are interested of it, I'll keep you posted regarding their reply.
neuralc said:Hi all,
In real life, all uP I see with that kind of power supply connected directly to the power line, have problems. Its always recomended to place a 1:1 transformer before, but if we use a transformer I beleive it is better to do a "traditional" power supply.

Thanks 'neuralc', your suggestion would be a great help in solving the problem. I have partly read the datasheets and it really fits the situation I asked. But I have some question regarding the function of HCPL-3700:
1. The datasheet indicated (from the reference schematic) a 115VAC input, would it be possible to input 220VAC? Can the chip manage it?
2. The supplied voltage (Vcc), would the output voltage depend on it? Let say Vcc (pin 8) = +5VDC, would the output at pin 6 (Vout) be also +5VDC-unregulated?
Regards.
