高效率和高頻直流到直流降壓開關穩(wěn)壓器 ETA鈺泰 ETA8156FT2G FCTSOT23-6
DESCRIPTION
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. 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.
