The LP8733xx is designed to meet the power management requirements in industrial applications. The device has two step-down DC/DC converters (which can be configured as a single dual-phase regulator or two single-phase regulators), two linear regulators, and two general-purpose digital-output signals. The device is controlled by an I2C-compatible serial inte.
