JW5223 Parameters Subject to Change Without Notice 2A, 6V, 1.5MHz Synchronous Step-Down Converter DESCRIPTION The JW®5223 is a current mode monolithic buck switching regulator. Operating with an input range of 2.5V-6V, the JW5223 delivers 2A of continuous output current with integrated P-Channel and N-Channel MOSFETs. The internal synchronous power switches provide high efficiency. At light loads, the regulator operate in low frequency to maintain high efficiency and low output ripples. Current mode control provides tight load transient response and cycle-by-cycle current limit. The JW5223 guarantees robustness with hiccup output short-circuit protection, start-up current run-away protection, input under voltage lockout protection, hot-plug in protection, and thermal protection.
