FB need COT Mode

Hi GARETH,

Could you explain what is FB COT mode?

For the input and output, the input current reaches 6.6A.

TPS61088 and TPS611781 are recommended for their current limit and FPWM mode.

Best Regards,

Fergus

Hi Fergus

Thanks for your suggestion

The feedback method requires Constant-On Time

Hi Gareth,

Could you tell me why need Constant on time control？

Is this due to the Vin close to Vout performance?

Above two devices are both Constant off time control.

Best Regards,

Fergus
