Block diagram
The figure below shows the block diagram of the programmer board. To provide the required safety
isolation level, the controller and interface circuits are isolated. The Micro-USB connector is isolated from
the microcontroller through the reinforced insulation of the DC-DC converter. The control circuits are designed
to meet the ELV safety standards and the interfacing devices are designed to meet the SELV safety standards.
Therefore, regardless of the isolation scheme used on the DUT Board, a safe isolation barrier is provided by the
programmer. Nevertheless, under all circumstances proper care must be taken while working with high voltage
applications.
