Part Number: PMP9766 I'm working with PMP9766 EV kit and during the testing I found a problem what is probably just an unfortune combination of components.
There is a DC/DC converter board based on MP1584EN integrated circuit (can't be replaced yet…
Part Number: PMP9766 Hi Sir,
Please check below figure for PMP9766 reference circuit.
Could we change the "D1" schottky to a normal diode component?
The purpose is to lower the super cap voltage level for capacitor life time extension.
If Vmain…
Part Number: PMP9766 Hi,
please check customer question below. thanks.
1. For PMP9766, VIN=5V (Vmain), and I need Vsys close to 5V when Vin drop. The output load current ~1.5A when VIN drop. can i change the R5=47Kohm?
Vout = [(R4/R5)+1]*Vfb…
Hi Bill, If I understand correctly, you want to know how does charging/discharging of the supercap works? The supercap is first pre-charged via diode, as shown in Figure 5 of PMP9766 (showed as "pre-charging operation" interval). When the supercap voltage…
Part Number: PMP9766 Other Parts Discussed in Thread: TPS552882 , TPS25940 I considering backup solution on 5Vmain / 6A, 300ms backup time condition based on PMP9766.
(Buck-Boost IC will change TPS552882, VCF: 4.75V)
Please let me know about two points…
Part Number: PMP9766 Other Parts Discussed in Thread: LP2998 Hi Sir,
If adopt PMP9766 module and change VIN (Vmain) to 5V and Vout (Vsys) to close 5V.
Do we need to change the design of cell balancing operation (LP2998 in EVM board)?
Thanks!
Part Number: PMP9766 Other Parts Discussed in Thread: TPS63020 Hi,
In the document of PMP9766, http://www.ti.com/lit/ug/slva726/slva726.pdf it says that it is "Small and high efficiency single converter solution" in section 6 Conclusion.
I'd like…
Part Number: PMP9766 Other Parts Discussed in Thread: LP2998 , TPS63020 , Hi,
I recently made this circuit and i am having some weird behavior. I made it as close as the original circuit but i changed the programmed output to reach 5V (R4 and R5,…
Part Number: PMP9766 Other Parts Discussed in Thread: TPS63020 , TPS63802 Hi,
I read the document of PMP9766. http://www.ti.com/lit/ug/slva726/slva726.pdf I want to use this reference design to charge the super-cap. However, during the charging operation…
Part Number: PMP9766 Other Parts Discussed in Thread: TPS63020 Hi,
I read the document of PMP9766. http://www.ti.com/lit/ug/slva726/slva726.pdf
It says that "The TPS63020 buck-boost converter operates bidirectionally and is able to transfer energy…
