Hello,
Datasheet P15 has equation(14) and use “Co(EFF) “.
“Co(EFF)2 should be the output capacitor but cutomer want to Know the meaning of (EFF).
Please advice the meaning of (EFF).
Regards.

Other Parts Discussed in Thread: TPS5420 I am using the TPS5420 as a voltage line and have an issue with noise. I get about 0.5 - 1.5 V pk-pk in noise. I used the TI calculator for the design. Would any1 have any tips to get this down as low as possible…
Other Parts Discussed in Thread: TPS5420 , TPS5430 , TPS54340 , TPS54240 Hi,
My customer would like to use TPS5420 on the following conditions.
We design it using " Using the TPS5430 As An Inverting Buck Boost Converter (Rev. A) ".
Could you please…
Other Parts Discussed in Thread: TPS5420 , SWITCHERPRO , TINA-TI , TPS5430 Hi, I'm doing a 3.3V design with TPS5420 these days. I'm trying to understand the open loop gain of TPS5420 buck circuit. However, with limited info from datasheet, it's difficult…
Other Parts Discussed in Thread: TPS5420 , LM2596 Hello, I used in my design TPS5420 and everything is well but I have Reset circuit with 555 and It supply nearly 3.6 Voltage and it last 4 seconds in my old design I used LM2596S-ADJ and When I connect this…
Other Parts Discussed in Thread: TPS5420 , TPS5430 I am hoping someone can clarify equation 11 on page 13 of the datasheet of the TPS5420. The design example calculates a ripple current of 143 mA but i am unable to calculate the same value. As far i can…
JohnTucker said: I see that you do have a rather long circulating path from PH to V104 cathode to L2 and back from C16 to ground.
Hi John,
comparing Sebastian approach with the TPS5420 EVM doesn't show big differences. Do you have a better proposoal to…

Other Parts Discussed in Thread: TPS54020 , TPS5420 , TPS5430 , LM25011 , TPS54240 Hello,
I've build a proto type board (breadboard) using the TPS54020 to load a supercap and it works fine.
Because of the high current, cycle-by-cycle limiting is occurring…
