2017/10/05 3A, 40V Asynchronous Step-Down Converter

General Description
The EC5116 is a current mode monolithic buck switching regulator. Operating with an input range of 4.5-40V,
the EC5116 delivers 3A of continuous output current with an integrated high side N-Channel MOSFET. At light
loads, EC5116 operates      in low frequency to maintain high efficiency and low output voltage ripple. Current
mode control provides tight load transient response and cycle-by-cycle current limiting.
The EC5116 guarantees robustness with input under-voltage lockout, start-up current run-away protection, output
short protection, feedback short protection and thermal protection. The EC5116 is available in 8-pin SOP package,
which provides a compact solution with minimal external components.
