26 / 32 page  Application information L6258EX 26/32 4.4 Notes on PCB design We recommend to observe the following layout rules to avoid application problems with ground and anomalous recirculation current. The by-pass capacitors for the power and logic supply must be kept as near as possible to the IC. It's important to separate on the PCB board the logic and power grounds and the internal charge pump circuit ground avoiding that ground traces of the logic signals cross the ground traces of the power signals. Because the IC uses the board as a heat sink, the dissipating copper area must be sized in accordance with the required value of Rthj-amb. |
