TPS51620 datasheet



The TPS51620 is a selectable dual or single-phase, fully compliant IMVP6+ step down controller with integrated gate drivers. Advanced control features such as D-CAP+ architecture and OSR overshoot reduction provide fast transient response, lowest output capacitance and the high efficiency. The device also supports single phase operation for light loads. The full complement of IMVP6+ I/O is integrated into the TPS51620. A logic signal is provided to control the number of active phases; transitioning into and out-of-dual-phase mode is exceptionally smooth. Adjustable control of VCORE slew rate and voltage positioning round out the IMVP6+ features.
