7.4.1 Active Mode

The TPSM846C24 device operates in continuous conduction mode (CCM) at a fixed frequency, regardless of the output current. For the first 128 switching cycles, the low-side MOSFET on-time is slowly increased to prevent excessive current sinking in the event the device is started with a prebiased output. Following the first 128 clock cycles, the low-side MOSFET and the high-side MOSFET on-times are fully complementary.
