TPS65105: Looking for a LCD bias solution

AClemotte

Part Number: TPS65105
Other Parts Discussed in Thread: TPS65100,

Hi,

I am proposing a LCD bias solution to my customer. The request are:

AVDD=12.5V@19mA
VGH=19V@0.5mA,
VGL=-10V@1.2mA

I checked TTPS65105, TPS65100. I've see that the difference between then is the minimum switch current limit. However, I am not sure which one should be our best fit to propose.

Would you please help to give me some recommendations?

Thanks!

Hello,

Since load currents in your customer application are rather low, TPS65105 with its lower switch current limit should be sufficient in this application. So you can suggest TPS65105 to customer.

Kind Regards,

Liaqat
