Part Number: TPS610986 Hello,
Updating design on a disposable medical device. Powered by SR44 high drain silver oxide cells with BOL = 1.5 and EOL = 1.0. Have placed 2 cells in parallel to lower the I2R losses.
Two questions.
1. Can someone provide…
Part Number: TPS610986 Other Parts Discussed in Thread: TPS61098 hi:
TPS610986, input 1.5V, output 3.3V, VSUB is followed by a load of 3-5mA,
MODE is low, some VSUBs have charging and discharging waveforms, and some have high levels.
How to understand…
Part Number: TPS610986 Hello, I am designing a battery-powered device with ultra low power requirements. The TPS610986DSER step-up is utilized for generating digital 3.3V supply from 2x alkaline or lithium AA cells i.e. the overall input voltage range…
Part Number: TPS610986 Hi TI expert
Can you help to check the below Inrush current is normal during power up?(with AAA battery x2) it's almost 2.5A on our measuring even in the no-load condition, it does not affect the function, just want to confirm…
Part Number: TPS610986 Hello Experts, I have a question about the over load protection. How the device will behavior when Vout(main) is shorted to GND directly in boost mode? My customer checked this by a following conditions, the coil was damaged. So…
Part Number: TPS610986 Other Parts Discussed in Thread: TPS61099 , TPS63900 Using TPS610986 in a wireless system with 200-300mA peak transmit current. when input voltage is ~3.4V the drop accross the regulator is ~400mV in bypass (both low power and Active…
Part Number: TPS610986 Hello Experts, My customer is evaluating their trial board. Customer mentioned that TPS610986 output in burst mode at light load (10uA) showed 3.5V by some boards. So customer would like to know how much variation of the output…
Part Number: TPS610986 Based on testing my system, I have to add a large output capacitance. While running, the battery contacts can disconnect from the PCB for a few milliseconds, which can cause the boost to drop and the MCU to brownout. I have a 330uF…
Part Number: TPS610986 Hi,
I'm Daniel from M2comm.
I had a question about TPS610986 :
I'd like to know its max output current for Vsub, I do know Vmain is 350~650mA, but Ican't find out detailed value about Vsub.
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…
