In another post, to this forum, I found the correct equation to use for R_LIM and Ioc (use the formula in the data sheet, not…
Other Parts Discussed in Thread: TPS40057 Hi
About TPS40057 OCP setting, there is a parameter, Vos, effect OCP huge range. Could reference attached file. Vos about -20~-120mV. How should we calculte OCP ? thanks~

Other Parts Discussed in Thread: TPS40057 Hi,
please can someone tell me the Max current sink/source to HDRV and LDRV of the TPS40057. Thanks,

Hi Soo,
Based on the information you mentioned, I think the OCP got tripped at low Vin due to the Rds,on increase at low gate drive voltage. By adding the schottky diode, the voltage drop from BP10 to BOOST got reduced, so the high-side gate drive voltage…
Other Parts Discussed in Thread: TPS40057 , TINA-TI Does anyone know how to obtain a transient generic SPICE, or unencrypted PSPICE model of the TPS40057? I am working on my own model, but if someone wants to share one they have already built maybe we…
Other Parts Discussed in Thread: TPS40054 my customer(Power-one) want to know the diference of operating model for TPS40054/55/57, please see attached document.
please explain in detail, thanks!
Other Parts Discussed in Thread: TPS40057 I have searched through the TPS40057 data sheet several times and can't find any data on the gate output current. the maximum and minimum voltages are specified with a 0.1A current. I assume this is rms. Does…
Other Parts Discussed in Thread: TPS40057 Hi, I am using TPS40057 for POL design, this POL has a parallel feature so I added additional circuit for it.
The POL works good individually, but output currents show 180 degree out of phase(like two sine waves…
