Hello,
I am assembling a circuit that will automatically switch on Street Halogen Lamp at night and switch it off during day. I ruled out using LDRs etc for this. Here's block diagram
[A/C Supply 240/50Hz] > [Xformer] > [Voltage Regulator IC] > [Timer IC] > [Counter] > [Logic IC] > [Triac/Relay] > [Lamp]
I am tired of repeating these first three stages of voltage step down and regulation whenever I try to assemble A/C power circuits,
(1) Isn't there a chip in market that combines these first three power supply stages into one, possibly based on rectifier and voltage divider circuit using diodes.
(2) NE555 won't power through a 3V button cell, would it? Atleast the datasheet said it wouldn't.
Thanks,
