- Page 4 High Efficiency Front-End DC-DC Converter PCB headers The PE25203 evaluation kit (EVK) has two types of PCB headers. 3-way PCB headers are used to configure the EVK. 2-way PCB headers are used to enhance the functionality of the EVK. Configuration PCB headers H2 and H3 PCB headers settings are loaded at IC power up.
- Page 5 Table 2. 2-way PCB header information. Sensing points Table 2 includes all the test points (TP) that can be found in the PE25203 evaluation kit (EVK). The aim of each TP is to facilitate users the capture of waveforms from critical signals, To make accurate measurements from input and output voltages, it is critical to use the SO and SI test points already included in the PE25203 evaluation kit (EVK).
