TPS566231/TPS566238 Step-Down Voltage Regulators

Texas Instruments TPS566231/TPS566238 Step-Down Voltage Regulators are simple, easy to use, high-efficiency, 6A synchronous buck converters in a QFN 9-pin 1.5mm x 2.0mm package. The devices operate with wider supply input voltage ranging from 3V to 18V. The D-CAP3™ control mode was adopted to provide a fast transient response, good line and load regulation, no requirement for external compensation, and to support low-ESR output capacitors.
