SLVS632K January 2006 – January 2024 TPS5430 , TPS5431
PRODUCTION DATA
The output voltage of the regulator is set by feeding back the center point voltage of an external resistor divider network to the VSENSE pin. In steady-state operation, the VSENSE pin voltage must be equal to the voltage reference 1.221 V.
The TPS543x implements internal compensation to simplify the regulator design. Because the TPS543x uses voltage mode control, a type 3 compensation network has been designed on chip to provide a high crossover frequency and a high phase margin for good stability. See the Internal Compensation Network in the applications section for more details.
