AH6957升降压电源芯片输入电压范围5V~24V（增加稳压电路还可以将输入电压范围到80v)，可以实现升压、降压、反相以及对称正负双电源输出。最大输出电流3A

升降压电源芯片

要求输入电压适配范围在5V~40V之间（可以适当缩小适配范围必须满足10V~26V之间），输出可调根据采样电阻而定。输出一般是13V、18v选择 。典型电路简单效率高，芯片廉价。要芯片型号。提供典型电路最好。（归纳一下就是升降压都行 输出两种电压）

Buck-boost power chip

The input voltage adaptation range is required to be between 5V and 40V (the adaptation range can be appropriately reduced and must meet between 10V and 26V), and the output is adjustable according to the sampling resistor. The output is generally 13V, 18v selection. The typical circuit is simple and efficient, and the chip is cheap. Require the chip model. It is best to provide a typical circuit. (To sum it up, both buck-boost and buck-boost can be output.
