The ISL9112 is a highly integrated buck-boost switching regulator that accepts input voltages either above or below the regulated output voltage. Unlike other buck-boost regulators, this regulator automatically transitions between operating modes without significant output disturbance.

The device is capable of delivering up to 1.2A output current and provides excellent efficiency due to its fully synchronous 4-switch architecture. A 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 ISL9112 supports a broader set of programmable features that may be accessed via 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.Read more
