The JW5231 is a current mode monolithic buck switching regulator. Operating with an input range of 2.5V-5.5V, the JW5231 delivers 1.5A of continuous output current with integrated P-Channel and N-Channel MOSFETs. The internal synchronous power switches provide high efficiency. Current mode control provides tight load transient response and cycle-by-cycle current limit.

The JW5231 guarantees robustness with hiccup output short-circuit protection, FB short-circuit protection, start-up current run-away protection, input under voltage lockout protection, hot-plug in protection, and thermal protection.
