PRODUCTION DATA.
The TPS6282x are synchronous step-down converters based on the DCS-Control™ topology with an adaptive constant on-time control and a stabilized switching frequency. It operates in PWM (pulse width modulation) mode for medium to heavy loads and in PSM (power save mode) at light load conditions, keeping the output voltage ripple small. The nominal switching frequency is about 2.2MHz with a small and controlled variation over the input voltage range. As the load current decreases, the converter enters PSM, reducing the switching frequency to keep efficiency high over the entire load current range. Since combining both PWM and PSM within a single building block, the transition between modes is seamless and without effect on the output voltage. The devices offer both excellent dc voltage and fast load transient regulation, combined with a very low output voltage ripple.
