4.1 Phase configuration selection

This EVM supports testing of both rails (RAILA and RAILB). The maximum number of phases available for RAIL A is seven phases and for RAILB is two phases. PWM6 and PWM7 pins share control for both rails. The GUI allows the user to enable or disable phases. (see Figure 7-8) See also the TPS53676 data sheet for more details. Select the jumper settings for phase configuration 7+0,6+1,5+2 as shown in Table 4-1 and Table 4-2.
