ADuM4070是一款稳压DC/DC隔离电源控制器，集成内部MOSFET驱动器。该DC/DC控制器原边内置一个隔离式PWM反馈，采用i Coupler芯片级变压器技术和完整的回路补偿。可以不必采用光耦合器进行反馈以及为了稳定性而补偿环路。
相比未经调节的隔离DC/DC电源，ADuM4070隔离器可以提供更加稳定的输出电压和更高的效率。它采用宽体SOIC封装，完全集成了反馈和环路补偿，提供更小的尺寸和8.3 mm爬电距离解决方案。稳压反馈可在整个输出功率范围内提供相对平坦的效率曲线。ADuM4070可从5.0 V或3.3 V输入电压使能具有3.3 V至24 V隔离输出电压范围的DC/DC转换器，输出功率达2.5 W。
应用The EVAL-ADuM4070EBZ can be used for different applications of the ADuM4070 isolated switching regulator. With the ability to be configured as a circuit with either single- (default) or double-supply output, the board supports a variety of input/output configurations and multiple transformer options. It is equipped with an ADuM4070 regulator for voltage isolation; the regulator features integrated feedback and a switching frequency that can be set from 200 kHz to 1000 kHz.
This user guide provides all the necessary details to set up and use the EVAL-ADuM4070EBZ board. Additional information about the ADuM4070 device is available in the ADuM4070 data sheet, which should be consulted in conjunction with this user guide when using the EVAL-ADuM4070EBZ board.
