DETAILED DESCRIPTION
Operation
The TPS6209x synchronous switched mode converters are 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 and voltage mode control.
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, the converter operates with its nominal
switching frequency of 2.8 MHz/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 having a seamless transition from
PWM to Power Save Mode without effects on the output voltage. Fixed output voltage versions provide smallest
solution size combined with lowest quiescent current. The TPS6209x family offers excellent DC voltage
regulation and load transient regulation, combined with low output voltage ripple, minimizing interference with RF
circuits.
PWM Operation
At medium to heavy load currents, the device operates with pulse width modulation (PWM) at a nominal
switching frequency of 2.8 MHz or 1.4 MHz depending on the setting of the FREQ pin. As the load current
decreases, the converter enters the Power Save Mode operation reducing its switching frequency. The device
enters Power Save Mode at the boundary to discontinuous conduction mode (DCM).
