TI公司的TPS51650和TPS59650是集成了兩個(gè)柵極驅動(dòng)器的雙路 VID全兼容的IMVP-7降壓控制器,支持CPU和GPU輸出,CPU通路具有一相,二相或三相,GPU通路具有一相或二相,8位 AC具有0.250V到1.52V的輸出,轉換電壓范圍3V到28V,主要用在IMVP-7 VCORE以及適配器,電池,NVDC或3V,5V和12V電源.本文介紹了TPS51650和TPS59650主要特性,方框圖,多種典型應用電路,以及TPS59650EVM-753評估模塊主要特性和指標,方框圖,電路,材料清單和PCB元件布局圖.

The TPS51650 and TPS59650 are dual-channel, fully SVID compliant IMVP-7 step-down controllers with two integrated gate drivers. Advanced control features such as D-CAP+ architecture with overlapping pulse support (undershoot reduction, USR) and overshoot reduction (OSR) provide fast transient response, lowest output capacitance and high efficiency. All of these controllers also support single-phase operation for light loads. The full compliment of IMVP-7 I/O is integrated into the controllers including dual PGOOD signals, ALERT and VR_HOT. Adjustable control of VCORE slew rate and voltage positioning round out the IMVP-7 features. In addition, the controllers’ CPU channel includes two high-current FET gate drivers to drive high-side and low-side N-channel FETs with exceptionally high speed and low switching loss.
