初级侧调节 PWM 控制器

初级端 PWM 控制器显著简化了需要 CV 和 CC 调节能力的电源设计。 FAN102 根据电源初级端的信息，精确控制输出电压和电流，不仅消除了输出电流检测损耗，而且无需任何次级反馈电路。具有低启动电流 (10 µA) 的绿色模式功能最大限度地提高了轻载效率，因此电源能够满足苛刻的待机功率调节。 与传统的次级端调节方法相比，FAN102 可在降低总成本、组件数、尺寸以及重量的同时提高效率、生产率和系统可靠性。 • 恒压 (CV) 和恒流 (CC) 控制（不带次级反馈电路） \n• 绿色模式： 轻载时的频率降低\n• 固定 PWM 频率 42 kHz，通过抖频解决电磁干扰 (EMI) 问题 \n• 恒压模式下的电缆电压降补偿 \n• 低启动电流： 10 µA\n• 低工作电流： 3.5 mA\n• 恒压模式下的峰值电流模式控制 \n• 逐周期限流\n• VDD过压保护（带自动重启）\n• VDD欠压锁定 (UVLO)\n• 栅极输出最大电压箝位在 18 V \n• 带自动重启的固定过温保护 \n• 采用 SOP-8 封装;
