LM5102: CCM mode issue

user5883945

Part Number: LM5102

Dears,

When the IC enters CCM mode, the output voltage will decrease. For example, when the output is set to 12V, only 10~11V is available in CCM mode

This phenomenon points to:

1. Too much voltage drop along the power path (PCB traces / inductor DCR / MOSFET conduction loss)

2. Problems in the feedback network design

3. Poor adjustment rate due to insufficient compensation
