Beschreibung

The JW5033 is a current mode monolithic buck switching regulator. Operating with an input range of 4.6V~18V, the JW5033 delivers 2A ofcontinuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency withoutthe use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripples.Current mode control provides tight load transient response and cycle-by-cycle current limit.The JW5033 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, input under voltag lockout.
