The STBB1-APUR is a buck-boost switching regulator IC from STMicroelectronics. It is a positive adjustable 1.2V 1 output 1.6A (switch) 10-VFDFN exposed pad device. The device is designed to provide a flexible solution for many applications, such as power management in a low-profile system, LED lighting, and step-down/step-up regulation in distributed power supplies. It features programmable current limiting, low quiescent current, and thermal protection. The device is available in a very small 10-VFDFN package with an exposed pad to improve thermal transfer and many other features that make it well suited for space constrained systems.
