TPS51620 用于 IMVP6.5 CPU/GPU Vcore 的单相 D-CAP+TM 模式降压控制器

TPS51620 描述

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 TPS51620 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. In addition, the TPS51620 includes two high-current MOSFET gate drivers to drive high and low side N-channel MOSFETs with exceptionally high speed and low switching loss The TPS51620 is packaged in a space saving, thermally enhanced 40-pin QFN and is rated to operate from -10°C to 100°C.
