LP873222RHDRQ1 Product Details

LP873222RHDRQ1 Description


The LP873222RHDRQ1 is designed to meet the power management requirements in automotive applications. The device has two step-down DC/DC converters, two linear regulators, and two general-purpose digitaloutput signals. The device is controlled by an I2Ccompatible serial interface and by an enable signal. The automatic PWM/PFM (AUTO mode) operation gives high efficiency over a wide output-current range. LP873222RHDRQ1 supports remote voltage sensing to compensate for the IR drop between the regulator output and the point-of-load (POL), thus improving the accuracy of the output voltage.
