Other Parts Discussed in Thread: TPS5420 , TPS5410 Do the TPS5420 and TPS5410 need a heat sink at there maximum current. My design used 3 TPS5420 and 1 TPS5410. So far during testing the resistors just get hot but the chips seem fine?
Thanks

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…
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…
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 , 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 for me to…
Other Parts Discussed in Thread: TPS5420 , TPS5430 , TPS54340 , TPS54240 Hi,
My customer would like to use TPS5420 on the following conditions.

Other Parts Discussed in Thread: TPS5420 Hello, I am using TPS5420 to convert 12VDC at 3.6VDC 2A. With them food a GSM modem (Sierra Wireless Q26RD). I connected the circuit suggested by the simulator SitcherPro. I wired the circuit to test it manually…
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…
Other Parts Discussed in Thread: TPS5420 , TPS5450 I have tried use another way to enable TPS5420 instead of using EN pin ( since when disable TPS5420 by pulling down EN pin, there is still around 1V output).
But even when Q16 is totally shut down…
