12 Layout

12.1 Layout Guidelines

Careful board layout is necessary due to the high transient currents and switching frequency of the converter. All capacitors must be soldered in close proximity to the IC. Connect ground and power ground pins through a short, low-impedance trace. A PCB layout proposal for a two-layer board is given in Figure 33. The bottom layer of the board carries only ground potential for best performance. The layout also provides improved thermal performance as the exposed lead frame is soldered to the PCB.

An evaluation module for the TPS60130 is available and can be ordered under product code TPS60130EVM-143. The EVM uses the layout shown in Figure 33 and components in Table 7.

The best performance of the converter is achieved with the additional bypass capacitors C5 and C6 at input and output. Capacitor C7 must be included if the large line transients are expected. The capacitors are not required. They can be omitted in most applications.

12.3 Power Dissipation

The power dissipated in the TPS6013x depends on output current and the mode of operation (1.5× or doubler voltage conversion mode). It is described by Equation 5.

Equation 5. TPS60130 TPS60131 TPS60132 TPS60133 equation_06_SLVS258A.gif

PDISS must be less than that allowed by the package rating. See Absolute Maximum Ratings for 20-pin PWP package power-dissipation limits and deratings.
