ISL911xx Family Of Buck-Boost/Boost Regulators

Renesas Electronics Corp.

The 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.

Linear Vs. Switching Regulators

Renesas Electronics Corp.

Linear RegulatorsLinear regulators are a great choice for powering very low powered devices or applications where the difference between the input and output is small. Even though they are easy to use, simple and cheap, a linear regulator is normally inefficient.Switching RegulatorsSwitching regulators on the other hand are highly efficient and available as modular chips which are compact and reliable. Switching regulators can be further divided into isolated and non-isolated.
