The default switching frequency of the TPS7H4010-SEP device is set at 500 kHz. For this design, the RT pin can be floating, and the TPS7H4010-SEP switches at 500 kHz in CCM mode. An RT resistor of 78.7 kΩ, calculated using Equation 13, Figure 7-12, or Table 7-1, can be connected from RT pin to ground to obtain 500-kHz operation frequency as well.
The TPS7H4010-SEP switching action can synchronize to an external clock from 350 kHz to 2.2 MHz. TI recommends connecting an external clock to the SYNC/MODE pin with a 50-Ω to 100-Ω termination resistor. The SYNC/MODE pin must be grounded if not used.
RT pin is floating and SYNC/MODE pin is tied to ground in this design.
