How to power FPGAs quickly, easily and cost-effectively with PMIC

If you are an engineer working on field-programmable gate arrays (FPGAs), you should be aware that the efficient operation of these devices requires an optimized power supply sequence. Using discrete components to meet these specific power requirements typically requires an additional discrete sequencer or microcontroller. However, for small form factor applications, finding the right part often increases cost, time, and even form factor, and thus does not meet customer specifications.

If you don't want to be so troublesome, consider the Power Management Integrated Circuit (PMIC). It has three main advantages:
• This is a single-chip solution that meets your entire system power needs.
• He provides power monitoring of all voltage rails, allowing you to verify that the power rail is within specification of the system.
• He offers a suitable package with better thermal performance to limit system temperature, which is especially important for industrial applications.

Consider using TI's flexible TPS65218 PMIC to meet the power needs of the latest FPGAs. It offers you three advantages in terms of flexibility: output voltage, sequencing and power monitoring for each rail. It features three adjustable step-down DC/DC converters, an adjustable buck-boost converter and an adjustable low dropout regulator (LDO). The adjustable output, along with the integrated sequencer, makes the TPS65218 ideal for both processors and FPGAs. This device is suitable for many applications, such as electronic point-of-sale devices, programmable logic controllers, home gateways, thermostats, elevator control panels and solar inverters.

The TPS65218's converter regulates the output voltage without the need for an external resistor divider network, allowing the power sequence to be fully configured without an external sequencer, helping to reduce bill of materials (BOM) size and cost .

In addition to the selectable output voltage, each converter can be assigned to one of 10 time slots or strobe pulses to create a custom power up/down sequence. This feature allows you to create solutions for different FPGAs, including either Xilinx Zynq-7000 or Max 10 and Altera Cyclone IV. The chart below shows an example of a power sequence.

Three Phase Isolation Transformer

Introduction:
Three phase dry type isolation transformer is a new generation of energy-saving power transformer developed by our factory from 300VA to 1600KVA on the basis of international similar products and in accordance with international and national standards such as IEC439 and GB5226. The winding adopts hole array winding. Vacuum impregnation is adopted for the transformer to make the insulation level of the transformer reach F or H, and the product performance reaches the advanced level at home and abroad. SG series three-phase dry type isolation transformers are widely used in circuits with AC 50Hz to 60Hz and voltage lower than 2000V. All these can be customized according to the different requirements of the end user.
Normal service conditions:
1. The altitude shall not exceed 2500M
2. Ambient medium temperature: ≥ - 25 ℃, ≤+40 ℃
3. Current and voltage waveforms are similar to sine waves.
4. No rain and snow erosion, no obvious shaking and impact vibration at the installation site.

5. No explosion hazard, gas and conductive dust.
