1 января 2018

The PMP40294 reference design is designed for a high capacity battery packs which requires more and more charging and discharging power. It can support a wide input voltgae (5~20V) from any adaptor and deliver the maximal charging current up to 3A to a 3S battery pack. By adopting the bi-directional buck-boost controller BQ25703A, the power stream can be flowed bidirectionally in the same power stage. In reverse mode, it can deliver 5/9/12/14.5/15/16/19/20V 3A from batteries to the port. The digital progemmability provides further extended functions as well.
