AI生成コンテンツ: Guidelines focus on optimal component selection, placement, and routing for IDTP9145 PMIC and IDTP9147/9148 DPUs to maximize performance. Minimizing parasitic inductance in PVIN power supply traces is critical, recommending parallel input capacitors to reduce ESL and output capacitors with proper voltage ratings to ensure regulator stability. The PVIN capacitor placement near inner-row PVIN pins requires short traces and multiple parallel vias to reduce parasitic effects. The IDTP9145 offers QFN and HLA packages, with HLA supporting 4-layer PCBs and easier via placement. Proper via arrays connect the exposed pad (power ground) to ground planes, ensuring effective current return. PCB layout examples emphasize minimizing ground plane perforation and careful via usage to maintain current flow and thermal performance.
