Description
The ARD_M_MPF_A3 is an Ease-of-Use focused power supply designed to provide power to Microchip PolarFire FPGAsfor 12 V applications. The design is scalable to support the most basic MPF050 devices with 48k logic elements to MPF500 devices employing 500k logic elements featuring 12.7G transceivers.
Features
- Design supplies all 9 voltage rails (Figure 1) to Microchip PolarFire FPGA device using one AmP PMIC (Figure 1)containing-
- Three sync buck switchers (C200) of 6 A capacity each
- One asynchronous buck switcher (C150) of 6 A capacity
- One LDO (C710) of 2 A capacity
- Inbuilt sequencer (C420) meeting PolarFire turn-on andturn-off timing requirements
- Soft start/shut-down
- Only one input 12 V (±10%) required
- Adjustable output voltage with down to 2.4 mV resolution
- 1% voltage accuracy
- Efficiency up to 90%
- QFN 5x5 sq. mm package
- Protections:Input Undervoltage Lockout (ViUVLO), Output Unde rvoltage Lockout (VoUVLO), Overcurrent Protection (OCP), Output Overvoltage Protection (OVP), Overtemperature Protection (OTP), Short-circuit Protection (SCP)
- Easy to change any voltage, currents or sequencing (if required) including enable/disable rails using web-basedWebAmp R.D and/or WebAmp software
- Power-good flag output and Enable input
- IC junction temperature range –40°C to +125°C
- Integrated design lending small PCB footprint
- Reference design rails meet or exceed Xilinx power performance requirements
Typical applications
- Commercial aviation markets
