Renesas offers a wide portfolio of high-performance buck-boost integrated FET regulators. The advantage of using a buck-boost solution is regulating the output voltage over the full power source voltage range. Buck-boost converter solutions usually have lower efficiency and a larger footprint than buck converter solutions.

Renesas' ISL911xx buck-boost regulator family is capable of working with the ultra-small inductors and capacitors to fit within less than 14mm2 board footprint, making them the ideal 2A switching converter solution for space-constrained mobile devices. The advanced wafer-level CSP package requires only a single inductor and very few external components, which minimizes overall space requirements. The ISL911xx regulators’ 2.5MHz switching frequency further reduces the power supply solution size.
