SC3055 is a high frequency, quasi-resonant flyback PWM converter with 650V GaN integrated (QR/DCM), which can achieve high efficiency and reliability. SC3055 provides an adaptive switching frequency foldback to achieve higher efficiency in the whole loading range. It operates in QR and DCM with valley switching for high efficiency. And at no load, the IC will operate in burst mode to reduce power consumption. SC3055 provides functions of low start-up current, low standby power consumption. The burst mode with extremely low operation current (350uA) can significantly reduce standby power consumption to meet the efficiency regulations. The converter integrates a segment power supply circuit for VDD power supply, which is especially suitable for applications with wide output voltage range. SC3055 offers comprehensive protections 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.
