JW5018 Parameters Subject to Change Without Notice 40V/600mA, 2MHz Synchronous Step-Down Converter DESCRIPTION The JW®5018 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the JW5018 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 JW5018 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.
