TMCS1100: Cases and documents that adopted TMCS1100 for DCDC current control

Part Number: TMCS1100

Hi,

TMCS1100 has a narrow frequency band, however I feel that it can be used for DCDC applications depending on the current control method.
Please let me know if you have any information on the adoption record and application notes at DCDC.

Koki,

The TMCS family is still a relatively new part family, and while our list of available collateral is growing, we unfortunately don't have any direct app notes in which implementation of the device in feedback control systems is the focus. I do tend to agree with you the device is a candidate in such applications, as the bandwidth of the control system is often much lower than the switching frequency of the topology. What I can share today is a few successful reference designs where the device has been implemented for your review:

1-kW GaN totem pole PFC and half bridge LLC: https://www.ti.com/tool/TIDA-010062 (TMCS1100)

4-kW digital interleaved CCM totem pole bridgeless PFC reference design: https://www.ti.com/tool/PMP40690 (TMCS1100)

In-phase current-sensing on 230-VAC for motor control: https://www.ti.com/tool/TIDA-010059#3
