2ED4820-EM EB2 2HSV48 Introduction to the 2ED4820-EM EB2 2HSV48 Key features • The evaluation board is able to deliver a continuous DC current up to 20A per channel It comes with a jumper-based configurability, to test various topologies. Warning: make sure to completely configure the jumpers before turning ON the power supply!! - Page 5 2ED4820-EM EB2 2HSV48 Introduction to the 2ED4820-EM EB2 2HSV48 Mandatory jumpers The 2ED4820-EM EB2 2HSV48 comes with two jumpers: J4 for supply selection and J17 for GND connection. Both jumpers have to be kept on the board for proper operation: Figure 4 Mandatory jumpers.

High voltage level shifter, to optionally drive the resistive path for capacitor pre-charge either from an MCU GPIO (P0.14_LSh) or from an external waveform generator (using TP23)
- Page 11 2ED4820-EM EB2 2HSV48 Table of contents Figure 14 End of charge detector. The voltage out of the resistive path, which is charging the capacitor, is compared to a reference voltage generated from the supply voltage supplying the board. R38 & R39 divide the voltage on the capacitor: CP+ is biased to 12/(270+12) = 4.255 % of OUT1 voltage.
