Descriptions
SC3058A is a high frequency, flyback PWM converter with
700V GaN integrated (QR/DCM/CCM), which can achieve
high efficiency and reliability.
SC3058A provides an adaptive switching frequency foldback
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 SC3058A 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. 描述SC3058A 是一款高频反激式 PWM 转换器，内置 700V GaN（QR/DCM/CCM），可实现高效率和高可靠性。SC3058A 提供自适应开关频率回退功能，以在整个负载范围内实现更高的效率。在重载或满载时，它运行在最高开关频率。当负载减少时，它以绿色模式和谷值开关方式运行以实现高效率。在无负载情况下，IC 将以突发模式运行以减少功耗。它具有低启动电流、快速启动、低待机功耗功能。突发模式下工作电流极低（240µA），显著降低待机功耗，以满足效率法规要求。SC3058A 提供全面保护功能，以防止电路在异常情况下受损。此外，频率抖动和智能驱动功能能够最大限度地降低噪声并改善 EMI 性能。
