The JW5211 is a current mode monolithic buck switching regulator. Operating with an input range of 2.5V-6V, the JW5211 delivers 1.2A 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 operates in low frequency to maintain high efficiency. Current mode control provides tight load transient response and cycle-by-cycle current limit.

The JW5211 guarantees robustness with hiccup output short-circuit protection, FB short-circuit protection, current run-away protection, input under voltage lockout, hot-plug protection, and thermal protection.
