SG6846A - Highly Integrated Green-Mode PWM Controller
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
