Retention Alternative Regulator, combines high efficiency in normal mode and ultra-low quiescent current for sleep mode
Overview
The RAR-eSR-qLR Retention Alternating Regulator combines two regulation sub-components: a high-efficiency 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
- High Efficiency (up to 95% peak efficiency)
