2. Recommended PCB Layout Guidelines
As a PCB designer, it is necessary to address critical issues in layout to minimize losses and optimize the performance of the power
train. Power Stage is a high power density solution and all high current flow paths, such as VIN (D1), PHASE (S1/D2) and GND (S2),
should be short and wide for better and stable current flow, heat radiation and system performance. A recommended layout proce-
dure is discussed below to maximize the electrical and thermal performance of the part.
