5V 2A SMPS Circuit Board

5V 2A SMPS Circuit Board used for DIY project.

5V 2A SMPS Circuit Board – 220V AC to 5V 2A DC Converter 

Open frame circuit board for 5V 2A SMPS. Can be used in batttery charging applications or in any other application requiring 5V 2A DC supply. Small in size, based on CT5503S Charging control IC with built in 800V/3A BJT for high voltage switching control. As claimed in the specifications, this circuit board is tested in house to deliver actual 2A of output current at a constant output of 5VDC.
