35W 48V LED indoor lighting

SMPS demo board 1736.0005

Flyback PFC 35W 48V

Dimensions 120x82mm


The 1736.0005 demo board by Magnetica is the ideal development platform for those applications requiring a unity power factor. Delivering up to 35W of continuative output power with a universal input mains range, it’s best suited in powering high brightness LED strings for indoor lighting. Circuital simplicity e usage of low-cost thru-hole components make this board a perfect platform to familiarize with PFC flyback topology using the ST Microelectronics L6562A PFC controller. It is also equipped with overload and short-circuit protection, and it is sold with complete technical documentation. Finally, on the PCB provision is made for optional circuitry in order to implement control of output current.
