说明

The TPS51611 is a fully IMVP-6.5 compliant single-phase synchronous buck 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 high efficiency. The TPS51611 supports both the Intel mobile CPU and integrated graphics modes with the integrated 7-bit DAC in Calpella platform. The TPS51611 provides the full complement of IMVP-6.5 I/O including VR_TT, DPRSLPVR, and IMON. Adjustable control of V_CORE slew rate and voltage positioning round out the IMVP-6.5 features. In addition, the TPS51611 includes two high-current MOSFET gate drivers to drive external FETs with low switching loss.
