YYM2338S

DESCRIPTION

The YYM2338S is a highly integrated 4-channel DC / DC regulator using SiP technology. the chip 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 YYM2338S 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 YYM2338S 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 YYM2338S uses an LGA package,size 8.5x8.5mm,provides a compact solution with zero external components, minimize PCB footprint and reduce product solution costs.
