  • Description

    The JW®5211 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 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 JW5211 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.

    The JW5211 provides output power good indication which is only available in SOT23-6 package.

    The JW5211 is available in 5-pin TSOT23-5、SOT23-5 or 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
