ETA2847
ETA2847 is 2A Synchronous Step-Down Converter manufactured by ETA.
DESCRIPTION ETA2847 is a wide input range, high-efficiency synchronous step-down switching regulator, capable of delivering up to 2A 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, ETA2847 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. An OVP function protects the IC itself and its downstream system against input voltage surges. ETA2847 is available in SOT23-6 Packages. FEATURES - Wide Input Operating Range: 4.5V to 28V - 34V Input Standoff Voltage - High Efficiency up to 90% - PFM Mode at light load - Capable of Delivering 2A - No External pensation Needed - COT Mode Control - Logic Control Shutdown - UVLO, OVP and Thermal shutdown - Available in SOT23-6 Package - Ro HS pliant APPLICATIONS - Smart Meters - Industrial Applications - Automotive Applications TYPICAL APPLICATION VIN 10u F 3 IN BST 6 ETA2847 SW 2 5 EN FB 4 GND 1 100n F 10u H 100K 22K VOUT=3.3V 22p F 22u F ORDERING INFORMATION PART No. ETA2847S2G PACKAGE SOT23-6 TOP MARK Pcs/Reel CHYW .etasolution.
