hi,
i think i need to get some parts from Mouser, that are not available from
Farnell, CPC, Conrad, RS etc. anyone want in?
separately, anyone got an LM323k or A or tried the new SPMS version someone
has put together? Anyone who uses 5v 3a linear will understand what i am
talking about, you find them in pinball machines c.1978-83.
The problem with the LM232k is the T03 package which is difficult to deal
with. The package needs significant heatsinking and the pins need
isolating carefully. It would probably be easier to just use a switch-mode
module which performs the same function - more efficient and easier to
use…
Not sure if there is anything I need from Mouser at the moment…
Cheers

i think thats right Alex and so i was in two minds to purchase the new SMPS version which is the same size etc. The heatsink on the device is substantial but i still think its operating at border line.
has anyone bought the SMPS, lm323 shape module, from the states or failing that can any recommend a really small smps, i do not have awful lot of room to play with and there is already a transformer in there.> On 13 Sep 2015, at 15:55, Alexander Lang alexanderlang1980@gmail.com wrote:

Raj,
If you add a heatsink to the switching regulator this module will do what
you want. Is the output from the transformer rectified? It should be if
you were feeding it to the input of an LM232…

hi,
yes rectified via Bridge from transformer secondary.
this is much cheaper than slapping a traco enclosed module to the back too.
plenty of space on the back to situate a heatsink once i remove the old one.> On 13 Sep 2015, at 16:04, Alexander Lang alexanderlang1980@gmail.com wrote:

What is the 5 Vdc supply for? The output from that module is not
particularly electrically quiet. If it is to power an audio or analogue
section it might need some filtering…

hi alex,
separate LDO for analog audio 15/-15 so thats no issue and i am always painfully aware of this. 5vdc is for a load of ttl and some bipolars.
there is some filtering already but i think 5vdc via some form of smps is the way to go.> On 13 Sep 2015, at 16:22, Alexander Lang alexanderlang1980@gmail.com wrote:

great ideas, i’ll think it through and come back. thanks
when space is not an issue i tend to drop huge plate of metal on to a steel can regulator but things are tight with this particular unit.> On 13 Sep 2015, at 16:25, Alexander Lang alexanderlang1980@gmail.com wrote:

hi alex,separate LDO for analog audio 15/-15 so thats no issue and i am always painfully aware of this. 5vdc is for a load of ttl and some bipolars.
there is some filtering already but i think 5vdc via some form of smps is the way to go.

What is the 5 Vdc supply for? The output from that module is not particularly electrically quiet. If it is to power an audio or analogue section it might need some filtering…

hi,
yes rectified via Bridge from transformer secondary.this is much cheaper than slapping a traco enclosed module to the back too.
plenty of space on the back to situate a heatsink once i remove the old one.

Raj,
If you add a heatsink to the switching regulator this module will do what you want. Is the output from the transformer rectified? It should be if you were feeding it to the input of an LM232…

i think thats right Alex and so i was in two minds to purchase the new SMPS version which is the same size etc. The heatsink on the device is substantial but i still think its operating at border line.has anyone bought the SMPS, lm323 shape module, from the states or failing that can any recommend a really small smps, i do not have awful lot of room to play with and there is already a transformer in there.

The problem with the LM232k is the T03 package which is difficult to deal with. The package needs significant heatsinking and the pins need isolating carefully. It would probably be easier to just use a switch-mode module which performs the same function - more efficient and easier to use…
Not sure if there is anything I need from Mouser at the moment…

hi,
i think i need to get some parts from Mouser, that are not available from Farnell, CPC, Conrad, RS etc. anyone want in?
separately, anyone got an LM323k or A or tried the new SPMS version someone has put together? Anyone who uses 5v 3a linear will understand what i am talking about, you find them in pinball machines c.1978-83.–
