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！

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 ...

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 ...

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 ...

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 ...
