SC3002 is a high performance, multi-mode fly-back PWM controller (CCM/QR/DCM). SC3002 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. SC3002 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 controller integrates a segmented power supply control circuit, which is especially suitable for applications with a wide output voltage range, reducing power consumption and greatly reducing peripheral devices. SC3002 integrated the adaptive over current protection (AOCP), which allows controlling the maximum output current from primary-side. The AOCP is specially designed for USB-PD solutions, together with PD controller, such as SC21xx serials. The AOCP can reduce the current stress of secondary synchronous rectification. The SC3002 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.
