BUCK-BOOST电路是一种常用的DC/DC变换电路，其输出电压既可低于也可高于输入电压，但输出电压的极性与输入电压相反。下面 ...

开关电源有Buck、Boost和Buck-Boost三大经典拓扑，其中Buck与Buck-Boost均可实现降压功能。 在ACDC电源中，输入电压一般是来自电网的85V-265V交流高压，而输出电压则是3.3V、5V、12V等直流低压，因此需要开关电源来实现降压。开关电源有Buck、Boost和Buck-Boost三大经典拓扑 ...

不知道大家在项目于上使用Buck-Boost芯片时，有没有这样的疑问：选用的明明是升降压变换器，也在单板上正常使用了，但是输出并不是负压！

方法二: Buck-Boost电路方法 如图3的 Buck-Boost方法实现生成负压的变换，当主开关Q 开通时，由于D反向，Vin 流过Q的电流只可以给电感L充电，如图4(a ...

此次，又利用解决怠速启停课题的升降压控制技术“Quick Buck Booster”，开发出凝聚了ROHM车载电源技术精髓的升降压电源芯片组。 该芯片组由具备 ...

Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

Aiming at automotive, Rohm has introduced a buck-boost dc-dc chipset, claimed to provide the lowest current consumption with good transient response for ECUs (electronic control units) for cluster ...

This is a switching regulator that supports buck, boost and inverting topologies, but perhaps it most notable feature is that it was first produced by Motorola in the early 1980s. This particular ...
