Part Number: TPS610985 Tool/software: Hi Sir,
My customer will use TPS610985 for their NiCd battery boost application. They want to know is there reverse polarity protection in TPS610985 input if their customer install the battery incorrectly, or any…
Part Number: TPS610985 Other Parts Discussed in Thread: TPS63900 , TPS63901 Tool/software: We have an existing design that uses the TPS610985 Ultra-Low Quiescent Current Synchronous Boost with Integrated Load Switch (3.0 volt output). We are refreshing…

Hi all,
In the datasheet on page 1, under features, it says "Minimum 350-mA switch peak current limit".
But later in the same page it says "The TPS61098x can provide up to 50-mA total output current at 0…
Part Number: TPS610985 Other Parts Discussed in Thread: TPS61098 Hi,
We are using TPS610985 in our device and 1F supercapacitor parallel to the boost converter TPS610985 as output capacitor in order to handle the high load for RF transmission. Our device…
Part Number: TPS610985 Hello. With such small currents, how should I go about getting accurate efficiency measurements of the TPS610985? I want to load it with 3uA, while supplying it with 1.5V.
Thank you!
Part Number: TPS610985 Hello,
I designed a new product that will use a single AAA battery cell to generate a 3.0V regulated power rail. This product will send some sensor data over the LoRaWan network and deepsleep the rest of the time. I use the TPS610985…
Hello Minqiu,
We have been doing some testing with the TPS610985 EVM and observed that in no load condition the device takes 20mA for 100ms during startup with initial spike of 37.4 mA.(VIN=1V, VOUT=VMAIN=3V, Low Power Mode) This is in no-load condition…

Tool/software: WEBENCH® Design Tools
Hi,
how reliable are the suggested layouts of webench?
As far as I know it's very important to place inductor and input/output caps very close to the IC. All that's not the case buy…
Hi Minqiu,
Do you have access to a development board for this DC-DC? If you do then you can see the same problem I am having by adding a 4 ohm resistor between the battery and the regulator.
Configure like this, 2.5V at the power supply, 4 ohms…
