LPC-826 came in today

[weeba2kv]

and what about peaks and spikes from net pollution ?

 

[Fiddy]

depends how good the "wall socket" regulation and filtering is.

 

[weeba2kv]

sigh lol ( net filtering ) never heard of that

 

[Fiddy]

what do you mean by "net"?
the electrical distribution system?

 

[weeba2kv]

yes 240 volt ac ( or 120 AC ) i never use adaptors always batteries

or a good lab power supply

 

[Fiddy]

Parts of a decent wall charger.

AC Input -> Step down transformer ->Rectifier -> Low pass filter -> Regulator -> DC Output.

but you wont understand most of that so there's no point explaining, the whole aim is to get relatively ripple free DC from AC.

 

[weeba2kv]

I do know what and how a wall charger works and i never use a wire-wound transformer those are terrible.

will a lpc 826 last long when run at 400mA with good heat sinking?

 

[billyblanko]

you could buy 10 LPC 826`s , set them all to run at 400ma`s & get 10 differant results for Duty Cycle , Power , Temperature blah blah ...you cannot give life expentancy`s for them .

there very very sensitive & only after killing a few do u realize how sensitive they really are .

you can kill 1 straight off the bat & another with identical inputs/variables can live for 100`s of hr`s

^thank you billyblanko, but is 400mA a safe current for it (I know 500-550 mA is the max)? will it immediately just die? (The 10 bucks the diode costs is about how much much i get each month so can't really just buy a new one! and yes I know it's not much but hey, I'm still a teen!!)

 

[billyblanko]

i`m running 1 @ 420mA`s , i`ve used it for minutes ...the best thing you can do is look at it this way , if u want to run it in the top end of its limitations then dont expect it to live 4eva, just stack the cards in your favour by providing adequate sinking & conservative duty cycle ...its a inexpensive diode , if it blows replace it .....i think u will be fine @ 400mA`s , but no 1 can give u a 100% gaurantee .
