It utilize a Pulse-Frequency Modulation (PFM) control scheme that implies high efficiency operation at light loads. There are two user-selectable over-current protection methods one provides over-current protection by taking advantage of the RDS(ON) of the P- Channel. The other provides accurate over-current protection with the use of an external sense resistor. The cycle-by-cycle current limit threshold can be adjusted with a external resistor.
