3 Example Schematic

Figure 3-1 shows the schematic diagram of the external CC/CV circuit board. The parameters are designed for the TPSM63610EVM and LM61495EVM to realize the CC/CV function. The constant current is 8A and the constant voltage is 5 V. For 5 V power supply, we choose to use the VCC on the EVM board for power supply rather than from the LDO.
