ETA8291 Dual 18V, 2A, High Efficiency Synchronous Step-Down Converter DESCRIPTION ETA8291 is a Power Management Unit(PMU) with 2 channels of wide input range, high efficiency DC-to-DC step-down switching regulators. Each channel is capable of delivering up to 2A of output current. It adopts an adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load. During light load, ETA8291 goes into a PFM mode that saves switching loss to achieve high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load. ETA8291 is available in DFN3x3-10 package. FEATURES  Wide Input Range: 3.
