ADVANCE INFORMATION for pre-production products; subject to change without notice.
The device offers spread spectrum clocking as an option. For the devices that have SSC enabled, the switching frequency is randomly changed in PWM mode when the internal clock is used. When the device is externally synchronized by applying a clock signal to the MODE/SYNC pin, TPS6281x-Q1 follows the external clock and the internal spread spectrum block is turned off. SSC is also disabled during soft-start.
