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
* Continuous output current: up to 2.1A (PVIN = 2.5V, VOUT = 3.3V)
* High efficiency: up to 9

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 1V or as high as 5.2V are supported. The ISL91127 is available in a 20 bump, 0.4mm pitch WLCSP (2.15mmx1.74mm) with a 2.5MHz switching frequency, which further reduces t
