Hi,
Are there any LED driver which can meet below requirement?
- Requirement -
Vin=12V+/-15%
Vout=14V max
If=0.5~1A
fsw=over 1.6MHz *need to avoid AM band
PWM dimming frequency=100kHz

Hi, Thank you for your reply. We checked TPS61500. According to datasheet 7.4.1, the IC needs several hundred microseconds to need regulate LED current. So we are thinking this IC can't meet 100kHz PWM dimming. Is there other IC which can meet their requirement?

Hi, Sorry for delayed reply. Thank you for your support. They can't provide detail of application, because it is confidencial information. But we guess it is something like a LED lighting. They need 100kHz PWM dimming against flicker. Are there any solution for their requirment?
