In the data sheet, Low-side switch sinking current limit is 2.3A.

Is this a DC or peak current?

Peak current.

Per the datasheet it is peak current, "The low-side MOSFET may also sink current from the load. If the low-side sinking current limit is exceeded the low-side MOSFET is turned off immediately for the rest of that clock cycle. In this scenario both MOSFETs are off until the start of the next cycle."
