ISL91106
ISL91106 is High Efficiency High Current Buck-Boost Regulator manufactured by Renesas.
Features
- ISL91106 with 3.8A switches
- ISL91106A with 4.2A switches
- Accepts input voltages above or below regulated output voltage
- Automatic and seamless transitions between buck and boost modes
- Input voltage range: 1.8V to 5.5V
- Output current (PVIN = 2.8V, VOUT = 3.3V):
- 2.1A (ISL91106A)
- 2A (ISL91106)
- High efficiency: up to 96%
- 45µA quiescent current maximizes light load efficiency
- 2.5MHz switching frequency minimizes external ponent size
