3A, 24V, 500kHz Synchronous Step-Down Converter
The RT8299A is a high efficiency, monolithic synchronous step-down DC/DC ,converter with internal power MOSFETs. It achieves 3A of continuous output ,current over a wide input supply range from 3V to 24V with excellent load and ,line regulation. Current mode operation provides fast transient response and ,eases loop stabilization. Cycle-by-cycle current limit provides protection ,against shorted outputs and soft-start eliminates input current surge during ,start-up. Thermal shutdown provides reliable, fault tolerant operation. The low ,current shutdown mode provides output disconnection, enabling easy power ,management in battery powered systems.
