TPS65150: How to process un-used functions

Tiger Yeh

Part Number: TPS65150

Hi ~

Customer changed LCD panel and don't want to modify layout.

Now, no more require VGH, VCOM and also no VGL input.

Could you please let me know how to setup these connections? Especial VGL for DRVL!

Suppose VGH and VCOM could be floating.

Thanks and Best regards,

Tiger

Hello Tiger:

So it looks like the customer will only be using the boost function from this device and not VGH, VGL or VCOM.

Referring to schematics in the user's guide at http://www.ti.com/lit/ug/slvuag5a/slvuag5a.pdf

they can make following BOM modification:

Use 0 ohm resistor at: C16, R8, R6, R3, C3

Remove following components: C15, R9, C25, C8, C11, R5, R4, R10, D2, D3, D4, D5, C12, C13, C17, C18, C20, C24

Kind Regards,

Liaqat
