he eta1486 is a wide input range, high-efficiency, dc-to- dc step-down switching regulator, capable of delivering up
to 4a of output current. current mode pwm control allows
the use of small external components, such as ceramic
input and output caps, as well as small inductors, while still
providing low output ripples. on top of the integrated
internal synchronous rectifier that eliminates external
schottky diode, eta1486 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. therefore, eta1486 is a much superior
solution in comparison to other competitions in terms of
efficiency and cost. overall, eta1486 is a highly efficient
and robust solution for dc-dc step-down applications that
requires wide input ranges.
eta1486 is available esop8 packages.
