Highly Integrated Green-Mode PWM Controller

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 peak current threshold for 1700ms, over-current protection is act
