ETA ETA8156
ETA8156 is a wide input range, high efficiency and high frequency DC to DC step-down switching regulator, capable of delivering up to 6A 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. ETA8156 is available in FCTSOT23-6 Package.DESCRIPTION
FEATURES
During light load, ETA8156 goes into a PFM mode that saves switching loss achieving high efficiency. An OVP function protects the IC itself and its downstream system against input voltage surges. ETA8156 is available in FCTSOT23-6 Package.● Wide Input Range: 4.5V-17V
