A range of integrated switching regulators from Intersil capable of operating in either Step-up (Boost) or Step-down (Buck) mode.
Feature
- Accepts input voltages above or below regulated output voltage
- Automatic bypass mode functionality
- Automatic and seamless transitions between buck and boost modes
- Input voltage range: 1.8V to 5.5V
- Selectable forced bypass power saving mode
- Adaptive multilevel current limit scheme to optimize efficiency at low and high currents
- Output current: up to 800mA (VIN = 2.5V, VOUT = 3.3V)
- High efficiency: up to 98%
- 41μA quiescent current maximizes light-load efficiency
- Fully protected for over-temperature and undervoltage
- Small 1.41mx1.41mm WLCSP
