摘　　要：传统的初级端控制器应用是利用光耦合器提供反馈回路隔离,利用分流调节器提供误差放大器和基准电压。设计人员设计隔离式AC-DC、DC-DC或DOSA兼容型电源模块时,面临着以更佳的性能应对市场需求的挑战。数字隔离器误差放大器可改进初级端控制架构的瞬态响应和工作温度范围。The traditional primary controller applications provide an optical coupler to provide feedback loop isolation, using shunt regulators to provide an error amplifier and reference voltage. When designers design isolated AC-DC, DC-DC or DOSA compatible power modules, they are faced with the challenge of better performance to meet the needs of the market. The Digital Isolator error amplifier improves the transient response and operating temperature range of the primary control architecture.
