Description

The main purpose of this evaluation board is to

show basic principles used for design of the power

supply and to give users a working prototype for

testing and daily use. The trend in recent years in

the supply of MCUs, CPUs, memories, FPGAs

etc. is to reduce the supply voltage, increase

supply current and provide various voltage levels

for different devices in one platform. A typical

example of this is the FPGA. FPGAs contain core

parts which operate with low level voltage,

interface parts placed between the core and the

output, system parts, etc. It is important to note

that each family of parts has a slightly different

voltage level and the trend is toward decreasing

voltage for each new family. The lowest operating

voltage currently is 1 V, and this can be expected

to drop to 0.9 V or 0.8 V in the near future. The

situation is similar with other parts of digital

solutions. Typically, the main CPU, memory, and

interfaces require different supply voltage levels.

Low operating voltage also bring another

challenge - transient. Digital devices are typically

sensitive to voltage level. If voltage drops below or

crosses over established limits, the device is

reset. This limit is typically ± 3 or 5 %. On the

other hand, digital device consumption can

change very fast (approx. several amps in several

hundred nanoseconds). The power supply must

be capable of reacting very quickly with a

minimum of over/under voltage, especially in

cases where very low voltage output is required.

There is additional stress placed on power

supplies in digital applications for industrial use.

The industrial standard bus is 24 V, but this

voltage fluctuates and the maximum required

input voltage level can be up to 36 V. Additional

surge protection is also mandatory for power

supply input in industrial applications. The

purpose of this evaluation board is to address all

of required parameters outlined above. This

means satisfying industrial input requirements

(operating voltage of up to 36 V) and generating

several output voltages for middle power

applications (up to several amps). The main

output voltage level can be set easily.
