LMQ644xx-Q1 采用具有可湿性侧面的优化增强型 HotRod QFN 封装, 增加了展频功能,并组装了四个 22nF 高频集成电容器,用于最大限度降低 EMI。 双随机展频 (DRSS) 跳频设置为 ±10%( 典型值),通过三角和假随机调制的组合大幅降低发射。 偏置引脚通过使用转换器输出为 LMQ644xx-Q1 供电,可降低器件功耗,实现 9μA 的空载静态电流,从而延长在电池供电系统中的运行时间。 LMQ644xx-Q1 即使在堆叠多个器件时也能保持高效率轻负载运行,从而在整个负载范围内实现 …

The LMQ644xx-Q1 is a 36V, synchronous, buck, DC/DC converter for high-current single or dual outputs.

使用MSP430F5172RSB40，封装为WQFN，给的layout图形上有散热焊盘，不知道这些散热焊盘需要接地吗？ 还是浮空就行. 一般来说，芯片底部的散热焊盘是要接地的， 并且大焊盘上可以 …

TCA9535 has two QFN package options; VQFN (RGE) and WQFN (RTW). These appear to be identical in pinout and performance, aside from the thermals and slight package height difference. Is there any other functional difference between TCA9535 VQFN and WQFN that I should take into consideration?
