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…
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…
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: LM76002 Other Parts Discussed in Thread: TPS62130 , 在为我的功放选择9V转±12V电源供电方案时,我需要一个buck芯片配置为反相buck-boost拓扑来提供负电压,我注意到了lm76002支持fccm模式和SYNC外部时钟同步,耐压和输出电流也符合我的要求,但是lm76002没有在数据手册中提到可以配置为负压输出,也没有应用手册,比如像tps62130/50那样(这两个的耐压水平不符合我的应用场景)。所以LM76002是否支持负压输出…
