This document describes the characteristic and operation of the Active Semi ACT5101EVK1-102 and ACT5102EVK1-102 evaluation kits (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data. The ACT5101EVK1-102 demonstrates the ACT5101QI102 power management IC. The ACT5102EVK1-102 demonstrates the ACT5102QI102 power management IC. Other ACT5101QIxxx and ACT5102QIxxx options can be evaluated on these EVKs by replacing the IC and any other necessary components.The two EVKs are very similar. The difference is that the ACT5101 output voltage is set by internal registers and it has A/D functionality. The ACT5102 output voltage is set by external resistors and it does not have A/D functionality. The setup and operation of the two EVKs are identical, so this document only references the ACT5101.The EVKs can be used as a standalone boards if desired. However, to access the internal registers and to take full advantage of the IC’s capability, the user must connect the EVK kits to a PC with Active Semi’s USB-TOI2C interface dongle and use the GUI software. The EVK provides full access to the each converter’s input and output voltage, as well as all the digital control signals. This gives the user the flexibility to configure the EVK to match their real world system.
