Overview

RAR-eSR-iLR-04 Retention Alternating Regulator enables this combination embedding two regulation sub-components: a switching regulator (eSR) and a linear regulator (iLR). A Regulation Control Unit (RCU) manages booting and transitions between each regulation functions.

Key features

  • Ideal regulator for power and voltage islets
  • Embedded RCU (Regulator Control Unit) to manage booting and mode transitions and to ensure data integrity
  • Configurable output drive before delivery to fit the application
  • Performances in sleep mode: accessible voltage reference can be used by wake-up circuitry
  • Performances in normal mode: PFM embedded mode allowing high-efficiency at low load
  • High Efficiency (up to 95% peak efficiency)
  • Low Bill-of-Material: fully integrated feedback and active compensation loop to reduce the number of additional external passive components
  • Low Output Ripple
  • Over-temperature/Over-current protected Output
