This Nano-power 4-output Single Inductor Multiple Output (SIMO) buck DC-DC converter provides a highly integrated power supply solution for ultra-low power applications that require both high efficiency and reduced footprint. The 4 outputs are fully configurable and can simultaneously supply several SoC power domains operating at different voltage values with high efficiency and low cross-regulation effect.

Key Benefits

  • - Highly integrated solution to supply all SoC domains (RF, analog, audio, IO, logic/MCU)
  • - Low quiescent current & high efficiency for extended battery lifetime
  • - Low BoM cost with a single inductor required
  • - Low applicative footprint
