I am looking to add 2 USB charging outlets to a new product. The PCB will be fitted internally within the product, and needs to fit within the available space. The board dimensions are 115mm x 24mm. The available space for mounted components is somewhat limited and is highlighted in the attached file 'pcb component space.pdf'. The position of the 2 USB outlets is also shown. There are also 4 small areas of the PCB where the PCB will be mounted to the product, and therefore no components can be positioned here (see file 'pcb mounting.pdf').
It is imperative that this USB charger be of a good quality as it will need to pass CE & British Standard (BS) certification by an independent testing organization. Quality components and adequate separation between high voltage & low voltage paths are crucial.
The input to the charger will be 110 - 240VAC (standard mains power). Ideally the power input will be on the right hand side of the PCB.
Output: 2 x USB dedicated charging ports, 5VDC +/- 0.25V, one port at 1A and one port at 2.1A
The charger should meet 30mW no-load standby power consumption requirement (five-star energy rating).
It should also incorporate a controller with over-current protection and auto restart.
The design needs to be compatible with common smartphones & tablets, including Samsung, Apple, Nokia, LG etc.
I am looking for freelancers with proven knowledge & experience of similar projects. My budget is towards the lower end of the $250-$750 range.
