The LP87725-Q1 device is designed to meet the power management requirements of the AWR and IWR MMICs in various automotive and industrial radar applications. The device has three step-down DC/DC converters, a LDO regulator and a load switch. The LDO is powered externally and intended for Ethernet device core supply. The load switch is intended to cut off the 3.3V IO supply during the sensor sleep mode. The device is controlled by an I²C serial interface and by enable signal.
