Part Number: TPS54339 Hi Sir,
My cusotmer use TPS54339 for 12V to 5V application.
Please check the waveform below. The left pic is the waveform as about circuit. The right one modify C85 to resistor for changint EN voltage level.
Would you…
Part Number: TPS54329 Other Parts Discussed in Thread: TPS54239 , TPS54339 , TPS54327 , , TPS54328 Hi Sir,
My customer would like to use TPS54329DDAR to replace TPS54339DDAR since the device shortage.
TPS54239 is an older device than TPS5433, right…
Part Number: TPS54339 Hi,
Are there minimum capacitance values or minimum start up times for this part? When I try to use a capacitor that is smaller than 6.2nF, the start up starts to look parabolic (left side of an upside down U) instead of a straight…
Part Number: TPS54339 Other Parts Discussed in Thread: TPS54335A , The following is the TPS54335A 5V to -5V circuit
Can TPS54339 use this circuit to achieve the -5V function?
Part Number: TPS54339 Other Parts Discussed in Thread: TPS54361 , TPS54360 Hi all
My customer has a design with the TPS54339, the spec is:
7V … 18V => 3.8V / 2.8A peak
They have an additional load capacitor of 450uF.
Can you comment if…
Hi,
Please advice if possible to limit the current? as noted, it is for max 3A as a default, can we limit it to 1.5A? if so, can you suggest how to do it?
Thank you in Advance,
When voltage is applied to the output with no input supply, the high side FET body diode can conduct and voltage appears on the input.. If it is high enough to turn on the IC, the TPS54339 can act as a boost converter and boost up the input to uncontrolled…
When you plug in Vac_adapter (to charge the battery), the Vsys voltage jumps from Vbat to near Vac_adapter voltage. This is a normal direct power path charger normal behave. According to your post, the question is about the TPS54339 Vout spike. So, I…
Hi Ahmed,
The LM3800 and TPS2420 are showing errors because PSpice files are encrypted ones and hence cannot be used for TINA-TI simulations.
However, TPS54339 has TINA-TI model in the product folder which runs fine in 9.3.150.328 SF-TI version…
