Additional Technical Information
TPS65552A
SLVS567 – JULY 2005
Figure 8 shows key points when designing a PCB.
1. In many DSC designs, parasitic resistance that cannot be ignored, exists on the power line path from the
battery to the primary side turn of the transformer. The TPS65552A has one ground point connection inside
the IC at the PGND PAD. So, the PCB layout should also keep a one-point ground connection at the PGND
terminal of TPS65552A.
2. The loop indicated by dotted-lines is laid out as small as possible to reduce the open area of the loop.
3. The TPS65552A uses the VCC input as a reference voltage. Considering Note 1, the ground of the power
unit that sources VCC is connected to PGND.
4. Regarding Note 3, the bypass capacitor, C2, is required to avoid grounding noise.
