Part Number: TPS610986 Hi,
Is the 22uF maximum recommended output capacitance mainly due to start up issues, or is it likely that >22uF will cause stability issues also during load regulation (0/50mA)?
My 3.3V output rail will have more capacitance…
Part Number: TPS610986 Other Parts Discussed in Thread: CC1310 , TPS610981EVM-674 Hello,
We have a custom design that uses a TPS610986DSE powering a CC1310. At power-up, we have seen reset issues with the CC1310 depending on the voltage level applied to…
Part Number: TPS61098 Hello team,
I am wondering what is the current limit in the VBUS output pin in TPS610981 and TPS610986 chipset??? I denoted that load switch on resistance in TPS610985/6 are 1.2Ohm (typical) and LDO dropout voltage in TPS61098/1/2/7…
Part Number: TPS63900 Other Parts Discussed in Thread: TLV61220 , TPS61094 , TPS63901 , TPS610986 We're powering off a 625mAHr coin cell so quiescent current is of course critical. The TPS63900/1 have very low quiescent current but high peak currents…
Part Number: TPS61098 I have 3V as input and i need 3.3V as output using " TPS61098" i tried in real life it only pass the input to the output and no boosting action.
Can somebody help?
I was planning to buy "TPS610986" but there were no stock…
Part Number: TPS61291 Other Parts Discussed in Thread: TPS610986 , Hello I used both the TPS610986 and TPS61291 boost converter in order to power a load that consume around 200mA in both situation (TPS610986 powering the load then use the TPS61291 to power…
Hi,
Since your output power transient of 3.3V*0.5A = 1.65W is greater than your input source power of 1V*0.02A = 20mW, your load will have to rely on the battery. If you need the undervoltage protection from the internal PFET between VSTOR and VBAT, with…
It sounds you need low Iq devices which minimize the drainage of your battery during sleep. You may consider TPS610986 for your 3.3V rail, and TPS61096A for your 12V rail. I also notify our experts of these devices and they may add comments.
I'm having trouble finding the actual efficiency numbers for the integrated DC/DC converter of the CC1310, is it somewhere in the technical manual? Also, would replacing the TPS782 with a TPS62740 allow for longer battery life, I think the software configuration…
