ETA8220
ETA8220 is High Efficiency Synchronous Step-Down Converter manufactured by ETA.
DESCRIPTION
FEATURES
ETA8220 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, 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, ETA8220 goes into a PFM mode that saves switching loss achieving high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load.
ETA8220 is available in SOT23-6 package.
