Nano power DC-DC converter in GF 22FDX with ultra-low quiescent current and high efficiency at light load
Key Benefits
- "Ultra-low quiescent current (300 nA) to ensure minimum current consumption in deep sleep / hibernation mode
- High efficiency at light load to extend battery lifetime (75% @ 10 uA)
- Low ripple value to supply noise sensitive and RF loads
- 1 uH inductor
- Ultra-small area for reduced silicon cost
- Configurable output current (depending on application requirements)"
