The TPS62088xx family is synchronous step-down converter that adopts a new generation DCS-Control (Direct Control with Seamless transition into power save mode) topology without the output voltage sense (VOS) pin. This is an advanced regulation topology that combines the advantages of hysteretic, voltage, and current mode control schemes.

The DCS-Control topology operates in PWM (pulse width modulation) mode for medium to heavy load conditions and in power save mode at light load currents. In PWM mode, the converter operates with its nominal switching frequency of 4 MHz, having a controlled frequency variation over the input voltage range. As the load current decreases, the converter enters Power Save Mode, reducing the switching frequency and minimizing the IC current consumption to achieve high efficiency over the entire load current range. In forced PWM devices, the converter maintains a continuous conduction mode operation and keeps the output voltage ripple very low across the whole load range and at a nominal switching frequency of 4 MHz. Because DCS-Control supports both operation modes (PWM and PFM) within a single building block, the transition from PWM mode to power save mode is seamless and without effects on the output voltage. The devices offer both excellent DC voltage and superior load transient regulation, combined with very low output voltage ripple, minimizing interference with RF circuits.
