JW5217 Preliminary Specifications Subject to Change without Notice 6V/2A Sync. Step-Down Converter DESCRIPTION The JW®5217 is a monolithic buck switching regulator based on COT architecture for fast transient response. Operating with an input range of 2.5V~6V, JW5217 delivers 2A of continuous output current with integrated P-Channel and 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. JW5217 guarantees robustness with output short protection, thermal protection, current run-away protection, and input under voltage lockout.
