I have ordered a 9V Step-Up Voltage Regulator after destroying a similar variable output device (don't ask and I won't tell). My motivation was that all I needed was 9VDC from 5.2VDC and the variable feature was unnecessary (and made the replacement cost higher).
In reviewing the specs, I noticed a 1.4A input maximum. I always understood that a device only drew what it needed from a larger, maximum supply current. This is being powered from a PC power supply at 5VDC. The supply is rated at 8A. Is this going to cause a problem? (Note that I hadn't hooked the earlier regulator to this power supply...)
As a little background, I had something working for years, but when I added a new device (Arduino Mega, drawing an additional 40mA), my system stopped working. That is when the manufacturer of the non-functioning device (an SSC-32 from Robotshop) suggested taking my 5.2VDC input, boosting it to 9VDC, so the mis-performing circuit could successfully regulate it to 5VDC. I thought it was strange (Boost 5V to 9V to regulate it to 5V?!?), but decided to give it a go since the manufacturer said it did not support 5.2VDC input.
I also suspect that the Mega couldn't talk successfully to the device at 115,200bps (although that speed is supported), so in addition to re-powering my system, I've configured communications to take place at 9,600bps.
So do you think I am OK with my Boost Regulator? What do I have to look out for?
