Combo voltage regulator designed in GF 22FDX, combining a linear regulator for active mode with an ultra-low quiescent regulator for low-power operation in sleep mode. A Regulation Control Unit (RCU) manages booting and safe transitions between each regulation functions to ease SoC integration.
Key Benefits
- Perfect fit for battery-powered IoT applications that require both high-efficiency during active mode and ultra-low power consumption in AON domain during sleep and deep sleep mode
- Support of input voltage from 1.9 V to 5.5 V (Li-Ion, USB supplies)
- Embedded RCU (Regulator Control Unit) to manage booting and mode transitions and to ensure data integrity
- Configurable output current to fit the application
