VIPer0P是一款离线交流变直流转换器,内部集成一个800V耐雪崩功率MOSFET和一个PWM控制器,在宽输入功率范围内实现7W输出功率。嵌入式零功耗模式(ZPM)让开关电源功耗在230VAC时低于4m W,按照IEC 62301标准定义,这个功耗值可视为零功耗。VIPer0P内部功能集成度很高,有助于设计人员设计一款轻巧的电源,同时节省组件成本。VIPer0P是一款设计灵活的功率转换器,适用于开关电源拓扑,例如,反激式转换器、正极或负极输出降压式转换器。该产品的宽输出电压范围(5V-30V)方便设计人员灵活地选用变压器。在诸多内部保护功能中,新的磁通量密度泄漏防护可防止启动过程中发生电流尖峰和变压器饱和现象。
VIPer0P is an offline AC-DC converter that integrates an 800V avalanche-resistant power MOSFET and a PWM controller to achieve 7W output power over a wide input power range. The embedded zero power mode (ZPM) allows the switching power supply to dissipate less than 4mW at 230VAC, which can be considered as zero power consumption as defined by the IEC 62301 standard. The high level of integration within VIPer0P helps designers design a lightweight power supply while saving component costs. VIPer0P is a flexible power converter designed for switching power supply topologies such as flyback converters, positive or negative output step-down converters. The product’s wide output voltage range (5V-30V) allows designers the flexibility to use transformers. Among the many internal protection features, the new flux density leakage protection prevents current spikes and transformer saturation during start-up.
