带GaN直驱的高频QR反激式PWM控制器

SC3021x是一款带GaN直驱的高频率反激式PWM控制器(QR / DCM)。SC3021x集成了高压电流源，具有x-cap放电功能。在启动时提供电流，正常运行时关闭。可以获得超低的待机功耗。SC3021x提供自适应开关频率折返功能，从而在整个负载范围内实现更高的效率。SC3021x工作在在QR和DCM模式时，开关管在谷底开通，以此来达到更高的效率。在空载时，IC将以突发模式运行，以减少功耗。SC3021x具有低启动电流、快速启动、低待机功耗等功能。突发模式具有极低的运行电流，显著降低待机功耗，从而满足效率规范。SC3021x集成了分段供电控制电路，特别适用于输出电压范围宽的应用，能够有效的 • 集成GaN直驱\n• 集成高压启动电路，Brown in/out检测\n• 集成x-cap放电功能\n• 内部软启动\n• 集成分段供电控制电路适用于超宽输出范围\n• 突发模式和故障模式：超低的工作电流\n• 自适应过流保护\n• 自适应环路增益补偿\n• 抖频改善EMI性能\n• 驱动能力：+100mA/-500mA\n• QR模式和DCM模式：谷底开关\n• Burst模式：轻载或空载\n• 内置过温保护\n• OTP支持支持外部NTC\n• 全面保护\n• SSOP 10封装;
