Dear all

I am looking for 2 power supply design low cost. let me know is there any supporting IC available .

1)Power supply : 24 VAC out put 12V DC 500mA / 5V 500mA

2) Power supply: Input 24-48 VAC/DC with 12V DC output 500mA /5V 500mA

here i would like use 7805/7812 regulator to get output.

I have seen https://www.rhydolabz.com/miscellan...-dcdc-buck-converter-power-supply-p-2310.html

LM2596 design but its DC-DC converter with Adjustable output. Is any design avilable which give above specification,

Is there any ready use module available.

 

Why you set on using the LDO ?
LDO regulate by dropping the power internally
so if your dropping say 12v to 5 v at 500mA .
the LDO will dissipate ( ( 12 - 5 ) * 0.5 = 3.5 Watts

switchers are your friend,
convert the raw AC to DC in a simple rectifier, and then an off the shelf DCDC module

this one is easy to use "at home"
as it has big pins

or there are very many other options
