Designed for low cost and high volume applications and using a TOP249 or TOP250 this compact converter uses a minimum number of parts to deliver a smooth DC output for power supply or battery charger applications.

Typical outputs are up to 35V at up to 10amps continuous (up to 27.0 volts) and 8 amps continuous from 27 to 35 VDC.  The prototype pictured has a variable output voltage control  (4 -35VDC)  and current limit (0.2 - 10.0 amps) .

Other outputs are available  12V - 15 amp,   18V - 15 amp,   48V - 5.5 amp,   110V - 2.5 amp.

Versions with all SMT (surface mount technology) control components on the bottom of the pcb - including a uP for multi-step charge control of lead acid, nicad, Ni-Fe, Li-ion and other battery types available on request.
