JW5359M
The JW5359, JW5359M, JW5359F and JW5359FM are monolithic buck switching regulators based on I2 architecture for fast transient response. Operating with an input range of 4.5V~18V, JW5359, JW5359M, JW5359F and JW5359FM deliver 2A 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, JW5359 and JW5359M operate in low frequency to maintain high efficiency.
JW5359, JW5359M, JW5359F and JW5359FM guarantee robustness with output short protection, thermal protection, current run-away protection and input under voltage lockout.
JW5359, JW5359M, JW5359F and JW5359FM are available in SOT23-6 package, which provides a compact solution with minimal external components.
