PRODUCTION DATA
The TPS62090Q synchronous switched mode converter is based on DCS-Control (Direct Control with Seamless transition into power save mode). DCS-Control is an advanced regulation topology that combines the advantages of hysteretic and voltage mode control.
The DCS-Control topology operates in Pulse Width Modulation (PWM) mode for medium to heavy load conditions and in power save mode at light load currents. In PWM, the converter operates with nominal switching frequency of 2.8 MHz or 1.4 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 quiescent current to achieve high efficiency over the entire load current range. DCS-Control supports both operation modes (PWM and PFM) using a single building block with a seamless transition from PWM to power save mode without effecting the output voltage. The TPS62090Q device offers excellent DC-voltage regulation and load transient regulation, combined with low output voltage ripple, to minimize interference with RF circuits.
