TPS51621 

Dual-phase D-+ ™ mode buck controller for core voltage of IMVP6.5 CPU/GPU

illustrate   The TPS51621 is an optional dual or single phase and is fully compliant with IMVP-6.5 step with an integrated gate driver controller. Advanced control features such as D-D + architecture and OSR overshoot reduction provide fast transient response and lowest output capacitance. The TPS51621 also supports single-phase operation with light loads. I/O with adequate supplementation of IMVP-6.5) included in TPS51621, including VR_TT, DPRSLPVR, PSI, and output current monitoring (select IMON). The PSI is designed to control the activity of the phase. The transition in and out of the two-phase mode is very smooth. Adjustable controlled slew rate and V-core-6.5 voltage positioning complete the IMVP. In addition, TPS51621 includes two high-current MOSFET gate drivers to drive extremely high-speed and low-switching loss high- and low-side N-channel MOSFETs.   characteristic   Available in double or single phase CPU or GPU mode is available Minimal number of external components Full IMVP - 6.5 features including VR_TT and output current monitor (IMON) >± 8 mV V-core accuracy/load/temperature 7-bit DAC Optimal efficiency is at light and heavy loads Patented Output Overshoot Reduction (OSR) reduces output capacitance Accurate, adjustable voltage positioning Available in 200/300/400/500 kHz frequencies Pat. To be automatically balanced phase balanced Optional 8-level current limit 3 V to 28 V conversion voltage range Fast MOSFET driver watts/integrated boost diode Integrated Overvoltage Protection (OVP) Small 6× 6, 40-pin QFN PowerPAD package apply IMVP - 6.5 V V Rails Core Application Adapter, Battery, NVDC or 3 V / 5 Gauge V / 12 Gauge
