请查看下面链接中的同步升压 FET 选择工具。 我们还为其他拓扑和应用提供类似的工具。 第二个链接指向应用手册、其中包含 TI 针对 FET 的所有基于网络的技术信息的链接。 此工具可让用户根据每千片价格、功率损耗或封装、对多达3种不同的 TI FET 解决方案进行比较。 "公式"选项卡包括用于计算功率损耗的所有公式。 正如我在之前的响应中提到的、CSD18540Q5B…
I can't say there is anything I know of that is "widely" used. This is not a common use case in automotive LED lighting. If you have the LDP5531EVM then I would probably modify it to see if you can achieve the desired output power. When…
您好，The sync buck converter needs to refresh the top FET driver BTST cap by turning on the low side FET. It can't achieve 100% duty ratio. The output voltage will have headroom from the input voltage. The power loss will also contribute to the headroom…
Part Number: TPS62913 Initially, I chose the TPS62913 as my buck converter chip to achieve better output noise performance, converting 15-17V to 3.5V. However, I overlooked one thing: our demo has a very light load (40mA@3.5V) and needs to control losses…
