DESCRIPTION
The JW?5250A is a monolithic buck switching regulator based on constant on-time (COT) control for fast transient response. Operating with an input range of 2.7V-6.0V, the JW5250A delivers 1A 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.
The JW5250A guarantees robustness with hiccup output short-circuit protection, FB short-circuit protection, start-up current run-away protection, input under voltage lockout and hot-plug in, and thermal protection.
The JW5250A is available in a 5-pin SOT23-5 package, which provides a compact solution with minimal external components.
