The JW5018B is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the JW5018B delivers 600mA 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 low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit.

The JW5018B guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.

The JW5018B is available in 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
