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.
