ISL9112
ISL9112 is 1.2A High Efficiency Buck-Boost Regulators manufactured by Renesas.
- Part of the ISL9110 comparator family.
features that may be accessed using an I2C bus interface. With a programmable output voltage range of 1.9V to 5V, the ISL9112 is ideal for applications requiring dynamically changing supply voltages. A programmable slew rate can be selected to provide smooth transitions between output voltage settings. The ISL9110 and ISL9112 require only a single inductor and very few external ponents. Power supply solution size is minimized by a tiny 3mmx3mm package and a 2.5MHz switching frequency, which further reduces the size of external ponents.
