TPS2066C: TPS2066C

Part Number: TPS2066C
Other Parts Discussed in Thread: TPS2062



In TPS2066c Fig 9 Rload is 2ohms and Vin is 5V, Vout is not following input voltage and Iout should have been 2.5A for 2 ohms load.

If my voltage source is 5V,5A then during short circuit entire 5A will flow into load, how TPS2066C responds to short circuit condition.

    Hi Pavaman,

    1. Figure 9 is in current limit condition.

    2. For short circuit condition, you can refer to figure 16. It will thermal cycle.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.

    Hi 

    Fig7, Fig 8 When enabled output took 4mSec after Vin > 3V,

    But in loaded condition in Fig 9 output responded in 1mSec. Why so ? Is it because of load in Fig 7 load is 1A and Fig 9 load is 2.5A. 

    i am little confused for higher loads the out responds in 1mSec. generally it should be reverse ? AM i right. ?

    In Fig 13 no output is shown in graph where by load is 2A. which is max for tps2062. Output should go High and then fall right ? may be in 4mSec.pls correct me.

    in Fig 11, output short there is not Vout , But when Iout=0 output is high. something is missing in me?

    Pavaman,

    1. For Fig7 and Fig9, you can refer to the position of arrow. That's the position to calculate the period. They are same.

    2. For Fig13, it's enabled into short. It means that output should always be 0.

    3. Short to GND, of course to be 0V.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    Thanks.
