The JW5018 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the JW5018 delivers 1A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in continual conduction to maintain low output ripples. Current mode control provides tight load transient response and cycle-by-cycle current limit.

The JW5018 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
