Overview

  • 12Vin design (no intermediary regulator required)
  • PMBus coverage for all critical rails
  • Proven solution for RFSoC (DAC and ADC) analog rails
  • Design can be easily scaled/modified for customer requirements
  • Common use of parts allow step and repeat for ease of design
  • Easy to use Quad PMIC module (25A per output) provides flexibility, high efficiency and fast transient response
  • MPM modules are fully factory tested solutions and require minimum engineering
  • MPM modules include inductors
  • Total system efficiency ~90%
  • Total solution size ~4 sq.in including input & output Caps
