Description
The JW5019 is a current mode monolithic buck switching regulator for LED driver. Operating with an input range of 3.6V~40V, the JW5019 delivers2A 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 ripples. Current mode control provides tight load transient response and cycle-by-cyclecurrent limit.The JW5019 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout.The JW5019 is available in 8-pin ESOP package, which provides a compact solution with minimal external components. The package has an exposed pad for low thermal resistance.
