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 ...

"做电源设计时，你是否遇到过这些场景？ 输入电压波动大，传统Buck或Boost无法覆盖。 既要升压又要降压，被迫使用两个电路级联。 效率低、成本高、PCB面积不够... 今天介绍的四开关Buck-Boost拓扑，只需1个电感+4个MOS管，完美解决所有问题！"--结尾有 ...

Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...
