envelope detector ic
The carrier frequency varies from several KHz to several Meg Hz, and the envelope is very low speed, kilo Herz and maybe even less. How do I design the
detector in analog? The signal is differential. Thank you.
I want to use common inductance first, and get into bridge rectifier, and then high frequency transformer. I want to let the transformer output 3 volts. 10v, 18v, -18v. Is this resonable? 5v supply is LM2576,the other two are 7815/7915.
I want to use 18v 30VA transformer, and then send the voltage to three ICs, 7815, 7915, LM2576-5, is it ok?
I worry the power consumption of LM2576 itself, because 18v input, and 5v output while 2A current. The power is 26W, could the heatsink abosrt the heat fully?

Search this board, I bet you would find tens of design you can copy and implement
I have serached before submitting this post, I havn't found them. I use the key words: regulator, power.
using something like 20 volt unregulated DC to get 2A 5V is rather unwise because it leads to much...
I want to get 3 power supply 5v/2A, +15v/0.3A, -15v/0.3A from ac 220v.
I think I should use transformer first(tranform to 15v or 5v?), and then rectify it. And then what should I do? and which regulator could provide 5v/2A? Thanks.
