HT7A6003 Evaluation Board : 19V/65W AC-DC Adapter
●General Description
■This Evaluation Board is designed to assist with power system design using the HT7A6003. As the HT7A6003 integrates many enhanced functions which do not require external function pin but operate automatically when the device is powered-on. Power system designers are not required to have extensive knowledge of these funtions but ragher just to focus their attention on peripheral circuit design and components selection issues. This simplifies greatly the power system design process and allows for faster time-to-market solutions.
■This Evaluation Board is an AC-DC adapter with a rating of 19V/65W and has an average efficiency of up to 87% at 90~265V. At its full Vac range, the maximum efficiency can be up to 88.6%. Standby power consumes less than 0.3W @ 115V and 230V Vac, and satisfies Energy Star 2.0 Spec.
■The specification, schematic BOM and PCB layout of the 65W Adapter are all provided in this Application Note.
