PRODUCTION DATA
The TPSM8286xA synchronous step-down converter power module is based on DCS-Control (Direct Control with Seamless transition into power save mode). This is an advanced regulation topology that combines the advantages of hysteretic, voltage, and current mode control. The DCS-Control topology operates in PWM (pulse width modulation) mode for medium-to-heavy load conditions and in PSM (power save mode) at light load currents. In PWM, the converter operates with its nominal switching frequency of 2.4 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 quiescent current of the IC to achieve high efficiency over the entire load current range. DCS-Control supports both operation modes using a single building block and, therefore, has a seamless transition from PWM to PSM without effects on the output voltage. The TPSM8286xA offers excellent DC voltage regulation and load transient regulation, combined with low output voltage ripple, minimizing interference with RF circuits.
