Retention Alternative Regulator, combines high efficiency in normal mode and ultra-low quiescent current for sleep mode
Overview
The RAR-iLR-qLR.01 Retention Alternating Regulator enables this combination embedding two regulation sub-components: a switching regulator (eSR) and an ultra low quiescent linear regulator (qLR). 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: qLR with low quiescent current: 0.2 µA
- Can supply always-on loads up to 300 μA
- 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
