AL17051 - ULTRA-LOW STANDBY POWER HV BUCK CONVERTER

General Description

The DIODES™ AL17051 is a universal AC high voltage input step down converter that provides accurate 3.3V or 5V output and outstanding dynamic performance and load regulation without requiring an optocoupler over line and load regulation.

Key Features

  • ultra-low standby operation power of 10mW. It also features high conversion efficiency 60% from rectified mains voltage to 3.3V or 5V for 50mA output and 50% at 10mA light loading during IoT system in idle and sleep mode. With high-degree integration of the embedded 700V High-Voltage MOS switches, the AL17051 is designed to reduce external components and minimize e-BOM (Bill-Of-Material) with small form factor package and PCB space. The AL17051 has rich protection features to enhance the system.
