概览

FAN604P 结合了准谐振 (QR) 控制和专属的具有受限频率变化的谷开关。QR 开关减少了开关损耗，因此提供了高能效，同时具有受限频率变化的谷开关会对频带进行界定，以克服 QR 开关内在的限制。FAN604P 具有突发模式运行，且运行电流极低 (300μA)，明显降低了待机功耗，可满足严格的能效规定，如 Energy Star 的 5 星级和 CoC 第 II 层规范。 FAN604P 包含一些用户可配置的功能，旨在优化能效、EMI 和保护。FAN604P 具有很宽的间隔频率范围，提高了轻型负载能效。它结合了用户可配置的功率限值参考 (PLR)，允许从初级侧控制最大输出电流，因此优化了变压器设计，提高了总体能效。它还包括了若干丰富的可编程保护特性，如过电压保护 (OVP)、欠电压保护 (UVP) 和外部触发的关断保护 (SD)。
