Part Number: TPS54428 Hi,
We are using GSM module in our design and power requirement for this is 4V @ 3A . We are using TPS54428 for supplying 4 volts to the module.Is it Right choice to choose this switched for GSM or i have to Choose Another switcher…
Part Number: TPS54428
Hi
My Customer has question. The customer says it can not be adopted unless the contents of the question clear. Please give priority to this question and respond.
Customer's spec is as follows. Vin =6V~17V Vout=1.2V Iout =2.7A
If…
Part Number: TPS54428 Hi team,
I'm using webench simulation of TPS54428, but it's not avaible to simulate it from IOUT=2.2A (VIN=5V/ Vout=3.3V) in the webench.
So, TPS54428 can't support the following conditions?
VIN = 5V
VOUT=2.5V / IOUT…
Other Parts Discussed in Thread: TPS54428 Dear Sir/Madam,
On page 12 of the TPS54428 datasheet section 8.2.2.2 Output Filter Selection table 2 specifies C8+C9 capacitance values (22-68uF).
The section discusses how L and C must be selected to ensure a…
I need to monitor load current. If I add a current sense resistor, in the 0.020 to 0.030 range after the output capacitor and then take the voltage feedback divider top from the load side of the current sense resistor, does that have the potential to…
Other Parts Discussed in Thread: TPS54428 We already have designs using this part in the regular buck configuration. Because we have used this part before and that our client has accepted it for their application, I'd like to be able to use the TPS54428…
Other Parts Discussed in Thread: TPS54428 Hello,
I have a customer wanting to use larger capacitance on the output, on the order of 200uF instead of the recommended 22-68uF. Unfortunately I do not have a schematic at this time but would be able to ask…
Other Parts Discussed in Thread: TPS54228 I check yhe thest thermal resistance value and see someting not reasonable for me.
For example, the tps54228 TJA (Junction-to-ambient thermal resistance) is show 45.3°C/W and the TJC (Junction-to-ambient thermal…
