USB cable 5V to 9V DC converter.

Post by Diabolo »

Hello,

Here is a cable (5.5x2.1mm) that can help you power your DS0150 from a USB charger, or power bank.
It is advisable to open the cable housing that is clipped and solder a tantalum capacitor 100uF-16V cmd 1206 on the output 9V output to perfect the voltage by removing the cutting ripple of the DC converter.

I open the USB connector, but there is a 100uF/16V titanium capacitor inside on the 9 Volt output.
At my Siglent 1102CML I can't see any ripple on the 9 Volt, maybe you have a cheap cable ?
CU, Rob

Hello,

Thanks for reply.
I bought 1 cord 5V to 9V, and 1 cord 5V to 12V and there was no capacitor 100uf on the DC output.
These cords are cheap and low price, and that's why I recommend to check if the 100uf capacitors are installed.
