Part Number: PMP9770 Hi,
For PMP9770 reference design, is possible to change voltage to support below LCD bias power?
1. For AVDD, we should change FB divider resistor to change output voltage.
2. For VGH/VGL, is it change D2/D3 zener diode to change voltage…
Part Number: TPS61085EVM-355 Other Parts Discussed in Thread: PMP9770 Hello,
We need to know if its possible to obtain another voltage values changing some electronic components to test and evaluate the TPS61085EVM-355 module.
We read the PMP9770 reference…
PMP9770 reference board.PDF OK. Then it looks the charge pump ckt is fit for your application.
Please take a look at the below circuit. The concept is the same.
Hi,
The input could be 5V or 12v(based on best solution to modify schematic), and I'm looking for PMIC like TPS65186, TPS65155 or reference design like PMP9770.
Please help to check is there any reference design or PMIC suitable, thank you very much…
Other Parts Discussed in Thread: PMP9770 Hi,
the reference design PMP9770 seems to be ideal for bias supply of the Tianma TFT we want to use.
Is it possible the get a demo board PMP9770 ? That would make our tests easier.
Regards,
Uwe
Dear Sasaki,
Yes, this circuit is non-isolated.
Please refer to the reference design PMP9770 at the TI website http://www.ti.com/tool/PMP9770?keyMatch=PMP9770&tisearch=Search-EN-Everything , just replace the TPS61085 with TPS61170, you can get both…
