ETA1663 Datasheet | ETA

DESCRIPTION FEATURES ETA1663 is a wide input range, high efficiency and - Wide Input Range: 4.5V-18V high frequency DC to DC step-down switching - Adaptive COT Control regulator, capable of delivering up to 4A of output - Ultra-Fast Load Transient Response current. It adopts an Adaptive COT control scheme that - Forced PWM Mode enables very fast transient response and provides a - Low Rdson Internal Power FETs very smooth transition when the output varies from - Capable of Delivering up to 4A light load to heavy load. The adaptive COT control also - Thermal Shutdown and UVLO maintains a constant switching frequency across line - Available in SOT563 and load. An OVP function protects the IC itself and its downstream system against input voltage surges. Short-circuit and thermal-overload protection APPLICATIONS improves design reliability. - 5G CPE ETA1663 is available in a tiny SOT563 package. - Set Top Box - LCD TV TYPICAL APPLICATION 100n F INPUT 12V Cin ENABLE INPUT 10u F Cin 100n F 1 VIN SW 2 5 EN FB 6 2.2u H Cff 47p F R1 optional 30K R2 6.8K OUTPUT 3.3V Cout 2- 22u F ORDERING INFORMATION PART No. PACKAGE ETA1663FSG FCSOT563 TOP MARK UXYW Pcs/Reel 5000 .etasolution.
