SRO-2.6∼4.2-0.7∼1.3 Power Management

Preliminary

High-Efficiency

Switching Regulator

Low BoM cost

 

Low power applications require efficient and compact solutions to adapt the voltage level to the operating mode and lower the power consumption.
The combination of an inductorless architecture and a low quiescent current makes SRO the appropriated companion to integrate with low power logic blocks.
Its low output ripple makes its compliant with most standard analog blocks, and its good power conversion efficiency makes it superior to an LDO to increase battery lifetime.

 

Key benefits

Optimum performances for low power applications:

  • Patent pending : superior regulation performance whatever the load current thanks to our proprietary double regulation loop (linear and digital)
  • Sleep mode (option) for ultra low quiescent current - around 5 µA
  • High efficiency maintained over input voltage range thanks to embedded multi-mode controller
  • Low switching frequency mode to maintain efficiency for very low current load operation
patent

Low Bill-of-Material:

  • Replace one costly inductor with two cheap ceramic capacitors.
  • Optimized in density for the best trade-off with the output current and input voltage range
  • Cost efficient solution compared to external Power Management Unit.

RECOMMENDED WITH

SRO is the ideal companion of SESAME Libraries and RAGTIME Memories
