ETA1471 28V/ 3A High Efficiency Synchronous Step-Down Converter
■ETA1471 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. With a fixed switching frequency of 500KHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors. ETA1471 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. The IC can stand off input voltage as high as 28V, making it an ideal solution for industrial applications such as LCD T V, Set Top Box, Portable TV, etc.
■ETA1471 is in FCTSOT23-6 and ESOP8 package.
●FEATURES:
■28V Input Standoff Voltage
■High Efficiency PFM mode at light load
■Capable of Delivering 3A
■No External Compensation Needed
■Current Mode Control
■Thermal Shutdown and UVLO
■Excellent Load and Line Transient Response
■FCTSOT23-6 and ESOP8 Package
