8.3.2 Synchronizing to an External Clock
The TPSM8281x can be synchronized by applying a clock on the MODE/SYNC pin. There is no need for any additional circuitry as long as the input signal meets the requirements given in the electrical specifications. See Figure 8-35. The clock can be applied, changed, and removed during operation. TI recommends the value of the RCF resistor be chosen such that the internally defined frequency and the externally-applied frequency are close to each other to have a fast settling time to the external clock. Synchronizing to a clock is not possible if the COMP/FSET pin is connected to Vin or GND. Figure 8-36 and Figure 8-37 show the external clock being applied and removed. When an external clock is applied, the device operates in PWM mode.
