11.1 Layout Guidelines

TPS24710/11/12/13 applications require careful attention to layout to ensure proper performance and to minimize susceptibility to transients and noise. In general, all traces should be as short as possible, but the following list deserves first consideration:

• Decoupling capacitors on VCC pin should have minimal trace lengths to the pin and to GND.
• Traces to VCC and SENSE must be short and run side-by-side to maximize common-mode rejection. Kelvin connections should be used at the points of contact with R_SENSE. (see Figure 39).
• Power path connections should be as short as possible and sized to carry at least twice the full load current, more if possible.
• Protection devices such as snubbers, TVS, capacitors, or diodes should be placed physically close to the device they are intended to protect, and routed with short traces to reduce inductance. For example, the protection Schottky diode shown in the typical application diagram on the front page of this data sheet should be physically close to the OUT pin.
