The TPS56X20 is a synchronous step-down (buck) converter with two integrated N-channel MOSFETs for each channel. It operates using D-CAP2™ control mode. The fast transient response of D-CAP2™ control reduces the required output capacitance required to meet a specific level of performance. The output voltage of the TPS56X20 can be set by either VFB with divider resistors (Adjusting the Output Voltage by External Regulation Mode) or I2C compatible interface (Programming the Output Voltage by Internal Regulation Mode).
When only external regulation mode is used in a TPS56X20 application, the VOUT terminal should be tied to the output voltage of the converter and SDA & SCL terminals should be grounded. A0 & A1 terminals may be floating.
When only internal regulation mode is used in a TPS56X20 application, the VFB terminal should be connected to the output voltage of the converter.
The integrated MOSFETs allow for high efficiency power supply designs. The MOSFETs have been sized to optimize efficiency for lower duty cycle applications.
