Below are some basic examples. Surprisingly, CPU cooling fans can draw a good bit of current. What i want some help with is making the voltage adjustable by somehow modifying the circuit. BrickbatOct 22, BassblasterOct 26, Windows 7 64 bit vs 32bit and RAM usage confusion?

Your power supply will not necessarily be the same, but this will give you an idea of the functionality of the IC. To view all product specifications available in these tables, click on the ” View Entire Datasheet” button.

2SD datasheet & applicatoin notes – Datasheet Archive

All information recommendations and suggestions appearing herein concerning this product are based upon data obtained from. Request Z- Communications D These examples should give you a good starting point for comparison to your power supply.


Just as a generic example. I think you will run into problems if you try to go above 17 volts. Are you sure that you want to delete this answer? Log in or Sign up. If the supply voltage to your pass transistors is 16 volts at full load a realistic value, although it could be somewhat higher the power dissipated by the transistors would be less than 25 watts at a 10 amp output.

One deluxe model I just looked at, needs 5-amps! The other thing to watch out for is power disipation: Ohhhh, of course i forgot about the VBE drops. If the voltage going to your series pass transistors is higher, the power dissipated will be greater.

The driver transistor would just need to send the outputs into full conduction, right?

Pin 4 is shown in your schematic as NC.


I Actually sat down for about 2 hours and successfully reverse engineered this power supply. With the pot disconnected pin dataaheet has 0V pin 6 has 7. I’m trying to use them to amplify the power in my circuit, used to drive a mini cpu fan. But if the output voltage was for example 5 volts the power dissipated would increase to about watts.

I would guess 5K after looking at page 4 in the datasheet i’ve been going back and forth between the datasheet and the unit i have and i cant say im making much progress with this. The IC uses a socket, so i bent pin 5 and 6 out of the socket and soldered the pot directly to the pins and still stuck at max voltage.

There is a lot of information about this voltage regulator IC. BassblasterOct 24, All Delta MCX connectors are available with gold- plated bodies, or with nickel- plated bodies for economy. Silicon diffused power transistor.

Depending on its use this can be an issue.
