LP873245-Q1 - Texas Instruments

LP873245-Q1 Dual High-Current Buck Converter and Dual Linear Regulator

The LP8732xx-Q1 is designed to meet the power management requirements in automotive 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 i.
