The ISL9110IRTNZ is a highly integrated buck-boost switching regulator capable of delivering up to 1.2A output current. It operates efficiently with an input voltage range of 1.8V to 5.5V and features a fully synchronous 4-switch architecture that allows for seamless transitions between buck and boost modes without significant output disturbance. The regulator achieves high efficiency, with a maximum of 95%, and has a low no-load quiescent current of 35µA, optimizing performance under light-load conditions. This device supports fixed output voltages of 3.3V and 5V, as well as variable output voltages down to 1V and up to 5.2V using an external resistor divider. The compact 3mm x 3mm TDFN package and a 2.5MHz switching frequency minimize the size of external components, making it suitable for space-constrained applications. The ISL9110IRTNZ is designed for standalone applications and is ideal for use in smartphones, tablets, and handheld devices. It includes protection features for overcurrent, over-temperature, and undervoltage conditions, ensuring reliable operation in various environments.
The ISL9110 and ISL9112 are highly-integrated buck-boost switching regulators that accept input voltages either above or below the regulated output voltage. Unlike other Buck-Boost regulators, these regulators automatically transition between operating modes without significant output disturbance.
Both parts are capable of delivering up to 1.2A output current, and provide excellent efficiency due to their fully synchronous 4-switch architecture. No-load quiescent current of only 35µA also optimizes efficiency under light-load conditions. Forced PWM and/or synchronization to an external clock may also be selected for noise sensitive applications.
The ISL9110 is designed for standalone applications and supports 3.3V and 5V fixed output voltages or variable output voltages with an external resistor divider. Output voltages as low as 1V, or as high as 5.2V are supported using an external resistor divider.
The ISL9112 supports a broader set of programmable 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 components. Power supply solution size is minimized by a tiny 3mmx3mm package and a 2.5MHz switching frequency, which further reduces the size of external components.
