The TPS51621 is an optional dual or single-phase, fully compliant IMVP-6.5 step integrated gate driver controller. Advanced control features such as D-Th+ architecture and OSR overshoot reduction provide fast transient response and lowest output capacitance. The TPS51621 also supports single-phase operation at light loads. Fully supplemented with IMVP-6.5 I/O) incorporated into TPS51621, includingVR_TT，DPRSLPVR，PSIand output current monitoring (select IMON.Proliferation Security InitiativeIt is used to control the activity of the number of phases. The transition in and out of dual-phase mode is very smooth.

Adjustable control of slew rate and V_core- 6.5 voltage positioning function, complete IMVP. In addition, the TPS51621 includes two high current MOSFET gate drivers to drive very high speed and low switching loss high and low side N-channel MOSFETs.
