SG6846A Description
The SG6846A is especially designed for SMPS with surge-current output, incorporated with a two-level OCP function. Besides the cycle-by-cycle current limiting, if the switching current is higher than two thirds the peakcurrent threshold for 1700ms, over-current protection is activated such that the SG6846A is latched off. If the switching current is higher than two thirds of the peak-current threshold for 100ms, and...
