CXSD61047B synchronous step-down DC/DC converter wide 4.5V to 23V input voltage range and 3.5A continuous load current capability.

The CXSD61047B is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3.5A continuous load current capability.

The CXSD61047B fault protection includes cycle-bycycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme which provides fast transient response. Internal Compensation function reduces external compensation components and simplifies the design process. In shutdown mode, the supply current is less than 1uA.

The CXSD61047B is available in an 8-pin SOIC package, provides a very compact system solution and good thermal conductance.
