Part Number: PMP9772 Other Parts Discussed in Thread: TPS61088 , , TPS40210 , TPS43061 Hi TI,
TPS61088 can give 12V,4.7A (56 W) output at 60 degree celcius for input range 6V - 8.4V (according to WEBENCH designer). But our input range is 2.5V-4.2V and…
Hi Brian,
Thanks for the update. Then TI design PMP9772 is just fit for your application. As there's a tiny boost to supply the Vin pin, so this TI design can support Vin low to 0.7V. Please read the PMP9772 carefully.
What is the Vo, Io in your application…

Helen-san,
Thank you so much for your advice.
I will introduce PMP9772 and confirm the schedule at the customer side. I may ask you on-line.

Hi Sir,
Very good question. If there's only battery in your system, then you need to add a tiny boost convert to boost the battery voltage to 5.5V, then use this 5.5V to supply the VDD pin. Like the TI design PMP9772 do.
Hi Uri,
you need two boost converter. one is TPS61088 for 2.5V to 12V power converting. the other is TPS613222A for the control circuit of the TPS61088.
The schematic is similar to this reference design. But change the output to 12V. http://www.ti.com…
Dear Saumil,
Since the charge pump output is added at the Vin pin, and the Vin's maximum stress can be 12V, so it is sure to be OK!
This is just a small analog circuit. Which is very commonly used in the power supply design.
For the TPS61088, its…
