Capacitor specifications, ripple current and life
What does the "Ripple current" and the "Life (in Hours)" in electrolytic capacitors specifications mean?
My intuition says it's the highest current it can handle and it can operate for that hours (when it works under that ripple current) before it…

Is it OK to power a laptop using a voltage regulator?
I am trying to build a power module to power my laptop using a 12V lead acid car battery.
The output specs on the laptop charger read 19.0.V and 3.6 amperes.
I have tuned a voltage regulator with following specs to provide 19V output, but it didn't…

Voltage drop when connecting DC-DC booster XL6009 to my solar panel generating 10 V constant
I have connected my solar panel (rated 6 V, 3 W), and it is generating approximately 10 V.
This 10 V is fed to an XL6009 to generate ~15-16 V, which is further fed to a 4S BMS to charge.
I checked that the open circuit voltage is 10 V, but when I…

What is the most efficient way to convert high Vin DC to low Vout DC?
I need voltage regulator to convert high range of Vin 20-60V to fixed 5 or 12V and the maximum output current is 200mA. What could be the efficient way to do this?
