EJW5116 3A, 40V Asynchronous Step-Down Converter

General Description

The EJW5116 is  a  current  mode  monolithic  buck switching regulator. Operating with an input range of 4.5-40V,

the EJW5116 delivers 3A of continuous output current with an integrated high side N-Channel MOSFET. At light

loads, EJW5116 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 EJW5116 guarantees robustness with input under-voltage lockout, start-up current run-away protection, output

short protection, feedback short protection and thermal protection. The EJW5116 is available in 8-pin SOP package,

which provides  a  compact  solution  with  minimal external components.
