Hi Leven,
Yes, TPS61196 or TPS92391 both can combine the FBx to support large current LED strings.

Hi,
My design (using the TPS92391) has a potential situation whereby during system shutdown, battery voltage (3-4.2V) may be present on the power input to the LED driver (so present at the VSENSE_N and VSENSE_P pins) , but the VDD…
Part Number: TPS92391 Section 7.3.8.5 Hybrid Mode of the TPS92391 datasheet, at the bottom of Page 25, states that:
"The PWM and current modes transition threshold can be set at 12.5% or at 0% brightness. The latter selection allows for pure current…
Hi Gary,
The current per channel is max 50mA. If you want 100mA /CH, please refer to below device.

Hi David,
I think you can consider our TPS92390/TPS92391 which have 4ch/6ch with 200mA max per channel.
And may I know what's the EE of customer?

Part Number: TPS92390 Other Parts Discussed in Thread: TPS92391 If Vin is 24V and assuming that LED string short-circuit is not possible, is it possible to have Vout higher than 48V, e.g. up to 70V? Same question for TPS92391.
Part Number: TPS92381 Other Parts Discussed in Thread: TPS61177 , TPS61196 , TPS92391 Dear Team,
Do we have any suitable solution can meet below backlight led spec?
Many Thanks,
Jimmy
Part Number: TPS61160 Other Parts Discussed in Thread: TPS61161 , TPS92391 Hi Team,
Could you check the max operation current for TPS61160?
Many Thanks,
Jimmy
