作者:时间:2012-05-11来源:网络收藏
TI公司的TPS51650和TPS59650是集成了两个栅极驱动器的双路 VID全兼容的IMVP-7降压控制器,支持CPU和GPU输出,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的输出,转换电压范围3V到28V,主要用在IMVP-7 VCORE以及适配器,电池,NVDC或3V,5V和12V电源.本文介绍了TPS51650和TPS59650主要特性,方框图,多种典型应用电路,以及TPS59650EVM-753评估模块主要特性和指标,方框图,电路,材料清单和PCB元件布局图.

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.
