I'm in need of a compact, simple linear power supply that converts common 110AC to 80-84DC. This system will be used as a charger for an ebike, and thus must be capable of handling approximately 100 watts. Key Requirements: - **Power Conversion**: The power supply should convert standard 110AC to a stable 80-84DC. - **Power Capacity**: It needs to support around 100 watts, sufficient for an ebike charger. - **Durability**: The physical design of the power supply should be robust, as it will be encased in thermally conductive potting. - **Size Constraints**: The casing of the power supply should be compact, as space is considerably limited. - **Mounting**: It should be designed for stand-alone use. Ideal Skills and Experience: - Expertise in designing compact electronic circuits - Experience with power supply design - Knowledge in thermally conductive materials and potting - Ability to create durable, compact designs. The power supply should include a DC barrel connector. The power supply is intended for indoor usage only. The power supply should be as compact as possible. The power supply should be as compact as engineering designs allow. The power supply should prioritize high efficiency in its design. The power supply should achieve an efficiency level above 90%.
