Text: National Semiconductor Application Note 1471 TK Man May 2006 Introduction Current limit protection can be implemented by measuring the voltage across the PFET’s RDS ON , thus eliminating the need for a sense resistor. The cycle-by-cycle current limit can be adjusted with a single resistor, ensuring safe operation over a range of output currents.
