High Performance Fly-back PWM Controller for USB-PD
SC3001 is a high performance, multi-mode fly-back PWM controller (CCM/QR/DCM). SC3001 provides an adaptive switching frequency fold_x0002_back to achieve higher efficiency in the whole loading range. At heavy load or full load, it operates up to maximum switching frequency. When loading decreases, it operates in green mode with valley switching for high efficiency. And at no load, the IC will operate in Burst mode to reduce power consumption. It provides functions of low start-up current, fast start-up, low standby power consumption. The burst mode with extremely low operation current (240uA) and significantly reduces standby power consumption to meet the efficiency regulations. The SC3001 offers comprehensive protection to prevent the circuit from damage under abnormal conditions. Furthermore, the features of frequency jittering and smart driving function can minimize the noise and improve EMI performance.
