Hi EM, I'm sorry, I have misunderstood.
It seems that a constant current circuit is realized using TLC272. Is this constant current circuit using TLC272 applicable to SEPIC of TPS55340?
Best regards, Dice-K
Other Parts Discussed in Thread: TLC272 , TPS6734 Hi
I have build a small test device with a TPS6734 12V step-up, a LC filter and 3 TLC272.
After a few hours of operation, all 3 opamps died and now show the same symptoms:
They work fine with a supply voltage…
Other Parts Discussed in Thread: TLC272 Hello,
I am currently testing an application that utlizes the TLC272 with a split supply with Vdd=+12V and the GND= -5V to create a negative reference voltage.
It is periodically failing.
The most likely culprits…
Other Parts Discussed in Thread: TLC272 , OPA348 , OPA2348 hi,
i am new here!
i am using a tlc272. the VDD is 5V and the VOH (High-level output voltage) is 3.8V.
we need to replace the TLC272 with an other amplifier to have VOH around 4.5V
it is a simple…
Thx, Emrys. Your solution forces me to redesign the PCB. I can replace the TLC272 with the comparator TLV9032DR. It has the same pin connections and is fast enough for the input of the 74LS107A. But I keep your idea in mind for future designs. Thanks…
Hi Wu,
take care, to assure that the output MOSFET goes into hard saturation, VOL at IOL=0A is specified for VID=-0.1V (differential input voltage) and for VIC=0.5V (common mode input voltage). With a much smaller VID or even a positive VID the input…

I am Trying to run the schematic in Tina, the output voltage produced is in mV is not as specified. I am attaching TSC file. …
Hi Yildirim,
in order to achieve a symmetrical output signal I have taken a OPAmp with a low offset voltage. And in order to achieve a full output swing I have taken a OPAmp with output rail to rail ability.
For experimenting you can use the TLC277 or…
