DCDC-ULP-LS-1.62-3.63-0.6-2.5.01_TSMC_40_ULPeF is a Nano power DC-DC converter in TSMC 40uLPeF with ultra-low quiescent current and high efficiency at light load, supporting 1.62 V to 3.63 V input voltage.
Key Benefits
- Ultra-low quiescent minimizing the current consumption in deep-sleep mode
- High efficiency at light load to extend the battery lifetime
- Low ripple level to supply noise sensitive loads
- 1 uH inductor
- Ultra-small area for reduced silicon cost
