Description: High Efficiency Buck-Boost Regulator

Features

* 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: up to 2A (PVIN = 2.5V, VOUT = 3.3V)
* High efficiency: up to 96%

Applications

* with a fixed 3.3V or 3.5V output voltage or adjustable output voltage with an external resistor divider. Output voltages as low as 1.0V or as high as 5.2V are supported. The ISL91127IR is available in a 20 Ld, 0.5mm pitch QFN (4mmx4mm) package. The 2.5MHz switching frequency further reduces the size
