JW5357/JW5357M Preliminary Specifications Subject to Change without Notice 18V/3A Sync. Step-Down Converter DESCRIPTION The JW®5357 and JW®5357M are monolithic buck switching regulator based on I2 architecture for fast transient response. Operating with an input range of 4.5V~18V, JW5357 and JW5357M deliver 3A 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, JW5357 and JW5357M operate in low frequency to maintain high efficiency. JW5357 and JW5357M guarantee robustness with output short protection, thermal protection, current run-away protection and input under voltage lockout.
