ETA1652 18V, 2A, High Efficiency Synchronous Step-Down Converter in SOT563
●DESCRIPTION
■ETA1652 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. lt adopts an Adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies frorm light load to heavy load.During light load,ETA1652 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 lC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 25, making it an ideal solution for industrial applications such as LCD TV, Set Top Box,Portable TV, etc.
■ETA1652 is available in SOT563 package.
●FEATURES:
■Wide Input Range: 4.5V-18V
■Adaptive COT Control
