1.3 Specification

The evaluation board default set up is configured for TEC control. TEC control is normally used for localized and precise temperature control which is a requirement for applications such as laser biasing or in-vitro diagnostics (IVD). The hardware on AFE539A4EVM is set up for such control. AFE539A4EVM is used to control the TEC through a DC/DC driver. The output of the device (pin OUT1 on the EVM) needs to be connected to the feedback pin of a buck-boost converter through a resister ladder.

The device software is not preconfigured, so registers need to be configured by using the GUI.
