TPS92200: power saving mode

Jaden Yue

Part Number: TPS92200

Hi Team,

When we control the IR LED from 0% to 100%,whether there is any power saving mode for TPS92200,like PFM. or the IR LED driver IC just have one mode-PWM mode?

Hi Jaden,

TPS92200 does not have PFM (pulse frequency modulation) when minimum on time is triggered. When minimum off time is triggered, it will change its switching frequency. You can refer to Section 6.6 Timing Requirements from the datasheet for these parameters.

Best Regards,

Steven
