My schematic is the same as TIDA-00690 eval board.
If I supply separetely TPS62122, the efficiency is about 80-85% but the context is different : with a power supply the DCDC is in "constant mode". With the harvester, we consider the transient of start…
Part Number: TPS62122 I have a 6.6 volt input for Vin and only 1 ma of current available limited by a constant current diode. My supply has 2 outputs 2.7 and 1.8 using 2 of the TPS6212s. I power up fine but if I raise the input power slowly or jiggle…
Part Number: TPS62122 Other Parts Discussed in Thread: TPS62120 , Hello , I am a French engineering student and for a project I am looking for the input impedance of the component TPS6212.
The idea is to represent the buck converter as a resistance…
Part Number: TPS62122 I'm surveying Buck converter. The condition is as below:
Buck converter: input voltage >= 7V, output voltage: 2V ,Iout>0.05A, ultra low Iq, smaller package.
Is TPS62122 the best solution? Thanks.
Part Number: TPS62122
In the data sheet of TPS62122, there says Output Current is 75 mA.
I have two questions for this output current.
1. Is this mean TPS62122's maximum capable current is 75mA? What happens is loader takes more current than…
Hi Sanika,
Most DC/DCs, including the TPS62122, have a UVLO circuit. This turns off the IC when Vin gets too low.
Using a higher Vin device for a single cell application is not typical, as the DC/DC is not optimized for the lower voltage. But they…
Part Number: TPS62122 Hi, looking for every option to save power in battery designs I would like to save the diode that typically sits between the battery (coin cells or whatever small stuff) and the power circuit.
This diode takes ~ 0.5V of my small…
Part Number: TPS62122 Other Parts Discussed in Thread: TPS61222 Hi,
Does TI have a power supply similar to TPS61222DCKT. The issue I am having with the TPS61222 is that the output voltage during shutdown is still present. I am looking for a power supply…
Thank you Excel Regidor . Can you kindly help us with the below questions also,
1) Could you please suggest the best TVS diode parameters for our case?
(Since the recommended operating voltage of TPS62122 is <15V, we are considering to pick a TVS…
