Texas Instruments TPS62893-Q1 Step-Down DC/DC Converter

Texas Instruments TPS62893-Q1 Step-Down DC/DC Converter is a synchronous converter with an I2C interface and differential remote sense. This DC/DC converter can operate in stacked mode to deliver higher output currents or to spread the power dissipation across multiple devices. The TPS62893-Q1 converter implements a fixed-frequency DCS-control scheme with adjustable switching frequency and adjustable loop compensation. This DC/DC converter is available in a 5.0mm x 6.0mm VQFN package. The TPS62893-Q1 device is AEC-Q100 qualified for automotive applications. This converter is ideal for ADAS sensor fusion, surround view ECU, hybrid and reconfigurable cluster, and head unit, telematics control unit
