DCDC--Burst Mode和Pulse Skipping Mode

1、Burst Mode和Pulse Skipping Mode（PSM）的区别

Burst Mode ≠ Pulse Skipping Mode，论坛有人认为Burst Mode就是Pulse Skipping Mode，这是不对的。

Burst mode是LTC凌特（现在ADI收购）的专利。

以LTC3624为例：

Burst Mode operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest voltage ripple.

To minimize VOUT ripple, pulse-skipping mode can be selected by grounding the MODE/SYNC pin. In the LTC3624/ LTC3624-2, pulse-skipping mode is implemented similarly to Burst Mode operation with the peak inductor current set to be at least 132mA. This results in lower ripple than in Burst Mode operation with the trade-off being slightly lower efficiency.
