DCDC control mode

Zhihong Huang

Hi team,

Now, the representative control mode of TI's DCDC is divided into three modes: voltage mode, peak current mode and Hysteretic current mode.

Is my classification correct?
Why do most of TI's DCDC products now use PCM control mode? What are the reasons for this?

Hi,

1. Maybe you are right, for step-down converter, constant-on time and peak current control are most popular.

2. Just some devices are of PCM mode, not always because of the control mode itself, but different controls have different appropriabilities of compensation/protection/corner control.

Thanks for your reply.

Do you have any slices which contain the DCDC hero product of the different control mode?
