12V to 24V @ 1A Step-up switching regulator using LM2585
Schematic Description This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments.
Dual USB Host/Hub Output with Constant Current Limit/Protection
This project has 2 outputs that enable us to power up 2 USB devices simultaneously from an input supply of 12-30V DC.
HV Nixie DC-DC Switching Power Supply
Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed.
Build your own 0-24V/3A Lab Power Supply with current limit
I have always believed that one of the best things about being a maker, is the ability to build your own tools, and we have covered the development of several tools like this in the past.
