多模式 PFC 和电流模式 LLC 组合控制器，提供可编程的降低音频噪声控制功能

HR1211 是一款多模式 PFC 和电流模式 LLC 数字组合控制器，可通过 UART 接口配置。其集成的节能技术有助于在整个工作电压范围内优化效率。PFC 控制器采用数字平均电流控制方案，以实现连续导通和断续导通混合工作模式。在重载下，连续导通模式可以降低 MOSFET 的峰值电流，扩大控制器的负载范围。在轻载下，断续导通模式可降低开关频率，以实现更高效率。突发模式采用可配置的数字软切换，可改善轻载效率，降低音频噪声。\n\n LLC 级采用电流控制模式，可以实现出色的稳定性和快速响应。根据不同的负载条件，可执行三种不同的运行模式：稳态模式、跳频模式和突发模式。通过这种方法，可以 • 稳态下工作频率高达 500kHz\n• 智能 X 电容在 AC 信号丢失时放电，符合 IEC62368 和 IEC60950 标准\n• 内置高压上电和 X 电容放电器\n• 为 PFC 和 LLC 提供数字控制\n• 为 LLC 提供电流控制模式\n• 针对 LLC 改善跳频模式控制，以降低音频噪声\n• 针对 LLC 实施自适应死区时间调节（ADTA）\n• LLC 容性模式保护\n• 可配置的软启动功能\n• 全方位保护：欠压保护/开启、过压保护（OVP）、过流保护（OCP）、开环保护（OLP）;
