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.
