DS3810MM 高效降压/升压转换器 完全可编程（通过 I2C）的高效率、高输出电流降压/升压转换器。 根据输入电压不同，当输入电压近似等于输出电压时，它们它会自动以升压、降压或全新的 4 周期降压/升压模式运行。

在定义的阈值内进行模式切换，避免不必要的模式内切换，以减少输出电压纹波。

两个可通过 I2C 访问的寄存器用于设置输出电压，VSEL 引脚用于选择哪个输出电压寄存器处于激活状态。 这样，这些器件就能够支持动态电压调节。 如果输出电压寄存器在运行过程中发生了更改或切换了 VSEL 引脚，则器件将以定义的可编程斜坡速率转换运行模式。

DS3810MM High efficiency buck/Boost converter Fully programmable (via I2C) High efficiency, high output current buck/boost converter. Depending on the input voltage, when the input voltage is approximately equal to the output voltage, they automatically operate in boost, buck, or a new 4-cycle buck/boost mode.

Mode switching within defined thresholds avoids unnecessary intra-mode switching to reduce output voltage ripple.

Two registers accessible via I2C are used to set the output voltage, and the VSEL pin is used to select which output voltage register is active. In this way, these devices can support dynamic voltage regulation. If the output voltage register is changed during operation or the VSEL pin is switched, the device will convert the operation mode at a defined programmable ramp rate.
