Description

The 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. Typical applications are power supplies for offline low power IoT (Internet of Things) devices that support WPAN (Wireless Personal Area Network) connectivity.
