Universal input reference design for 12-V lead acid battery charger

This reference design takes a Universal AC input (85 VAC - 265 VAC) and converts to a 17.5-V isolated output using a PSR flyback topology. It is then followed by a battery charger circuit, which outputs up to 15 V to a lead acid battery. This is a fast-charge design capable of delivering 12 V @ 2.5 (...)
