AL17052中文资料700V Buck Converter With Small Inductor数据手册Diodes规格书

描述 Description

The AL17052 is a universal AC high-voltage input step-down converter that provides accurate 5V output and outstanding dynamic performance and load regulation without requiring an opto-coupler over line and load regulation. Typical applications are power supplies for offline low-power IoT (Internet of Things) devices that support WPAN (wireless personal area network) connectivity.


To support always-on requirements of IoT connectivity, the AL17052 features ultra-low standby operation power of 10mW. It also features high conversion efficiency 60% from rectified mains voltage to 5V for 50mA output and 50% at 10mA light loading during IoT system in idle and sleep mode.


With integration of embedded 700V high-voltage MOS switches, the AL17052 is designed with high degree of integration, which requires supporting less electronic components to form minimum e-BOM (bill-of-material) with small form factor package and PCB space.


The AL17052 has rich protection features to enhance the system safety and reliability. It has overtemperature protection, VCC undervoltage lock function, overcurrent protection, overload protection.


The AL17052 is available in the SOT25 package.
