STEVAL-PSQ001V1 Power management for CPU, FPGA and memory based on the PM6680A Data Brief Features Input: 5 - 36 VDC, surge protection Output voltages: ­ Output1 (Vcore) selectable from: 0.9, 1.0, 1.2, 1.5, 1.8 or 2.5 V, 4 A continuously (6 A peak), tolerance: 3% ­ Output 2 (Vi/o) selectable from: 1.0, 1.2, 1.5, 1.8, 2.5 V or 3.3 V, 2 A continuously (3 A peak), tolerance: 3% ­ Output3 Vsys: 3.3 V 0.4 A (0.8 A peak), tolerance: 4% ­ Output3 Vaux: 2.5 V, 0.4 A, tolerance: 2% Analog 5: 5 V, 0.8 A, tolerance: 4% Analog 3.3 V: 3.3 V, 0.15 A, tolerance: 2% STEVAL-PSQ001V1 Description reset. This limit is typically ± 3 or 5 %. On the other hand, digital device consumption can The main purpose of this evaluation board is to change very fast (approx. several amps in several show basic principles used for design of the power hundred nanoseconds). The power supply must supply and to give users a working prototype for be capable of reacting very quickly with a testing and daily use. The trend in recent years in minimum of over/under voltage, especially in the supply of MCUs, CPUs, memories, FPGAs cases where very low voltage output is required. etc. is to reduce the supply voltage, increase There is additional stress placed on power supply current and provide various voltage levels supplies in digital applications for industrial use. for different devices in one platform. A typical The industrial standard bus is 24 V, but this example of this is the FPGA. FPGAs contain core voltage fluctuates and the maximum required parts which operate with low level voltage, input voltage level can be up to 36 V. Additional interface parts placed between the core and the surge protection is also mandatory for power output, system parts, etc. It is important to note supply input in industrial applications. The that each family of parts has a slightly different purpose of this evaluation board is to address all voltage level and the trend is toward decreasing of required parameters outlined above. This voltage for each new family. The lowest operating means satisfying industrial input requirements voltage currently is 1 V, and this can be expected (operating voltage of up to 36 V) and generating to drop to 0.9 V or 0.8 V in the near future. The several output voltages for middle power situation is similar with other parts of digital applications (up to several amps). The main
