If you need to know whether a 5v to 12v DC-DC convert is good, there are many factors to consider before answering. There are different types of voltage regulators used today. The first is called a system on a chip, SoC, calling on linear regulators. Low dropout, LDO, regulators and switching regulators (DC-DC converters) are also on the menu.
Using LDOs to generate low voltages via the power supply
burns power relative to the drop in voltage that occurs as it passes from input
to output. If you have a high drop, then the LDO is not an efficient way to go.
Instead, you might rely on a 5v
to 12v DC-DC converter.
The switching noise is a problem, however.
If you have a highly sensitive device, forget about the
DC-DC converter. Instead, you may need to cascade a DC-DC one and then use the
LDO afterward to reduce the noise. By combining products, you can reach the
desired results. There are two types of DC-DC converter (12v-5v) technologies. The first is the Standard Inductor-Based
DC-DC Converters which require an external inductor and capacitor to create the
DC output level.
The next is the Switched-Capacitor DC-DC Converters which
can be used with on-die capacitors. They cannot generally supply as much
current as inductor-based solutions, though. Additionally, DC-DC converters can
be used in the following modes: Buck mode, Boost mode,
Bypass mode, Combination mode. To learn more, check out a professional
