降压式转换器
JW5392F
The JW5392 and JW5392F are monolithic buck switching regulators based on I2 architecture for fast transient response. Operating with an input range of 4.5V~18V, JW5392 and JW5392F 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, JW5392 operates in low frequency to maintain high efficiency.
JW5392 and JW5392F guarantee robustness with output short protection, thermal protection, current run-away protection and input under voltage lockout.
JW5392 and JW5392F are available in SOT563 package, which provide a compact solution with minimal external components
