The TPS62865 and TPS62867 synchronous step-down converters use the DCS-Control (Direct Control with Seamless transition into Power Save Mode) topology. This is an advanced regulation topology that combines the advantages of hysteretic 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 2.4-MHz nominal switching frequency, having a controlled frequency variation over the input voltage range. Since 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 does not affect on the output voltage. The devices offer both excellent DC voltage and superior load transient regulation combined with very low output voltage ripple.
