The TPS51513 is a synchronous buck controller for a single-phase integrated gate driver. Advanced control features such as the D-+ architecture and OSR™ overshoot reduction provide fast transient response, low output capacitance, and high efficiency. TPS51513 supports application-enabled bit DACs and integrates 3 wide range IC V-cores. It also provides a full signal I/O including Sleep Mode Control (SLP), two power supplies for good signals (POOD and, and Analog Current Monitor (IMON). The logic input is compatible with or 1 - V or 3.3 V logic levels. A resistor controlled by the slew rate of the V core. In addition, TPS51513 includes a high-current FET and an integrated P/N junction diode gate driver to drive a low-switching loss N-channel FET.
