Hi，Now i confirmed it's a over current protection.
Channel 1:TPS40090 SS
Channel 2:TPS40090 PWM1
Channel 3:TPS40090 ILIM ，Set to about 473 mV
Channel 4:INA849 CS1，【I connect the CSCN directly to AGND finally】
When PWM continued ，CS1 wave strange …
Part Number: TPS40090 Tool/software: Hey Multiphase Buck Team,
I have a customer evaluating the TPS40090 for a new project and we were hoping you could help to provide feedback on the inquiry below!
It is our understanding that if the CS inputs go beyond…
Part Number: TPS40090 I am trying to connect external error amp. to Idroop pin(Shorting FB and Comp pin), could you let me know what the max voltage we could provide to Idroop, would it give any over voltage error if idroop voltage goes above 0.7V. Plan…
Part Number: TPS40090 Tool/software: Why is the falling edge of the DCR Current Sense waveform not a smooth downward straight line, but a rising and falling line? The actual waveform shown in the figure has a period of 3.5us and a rising edge of about…
Part Number: TPS40090 Other Parts Discussed in Thread: PMP9637 hi,
I need some advise that when i designed a DCDC boost supply with TPS40090, from 35VDC to 116VDC, 2 channel interleave which used PWM1 and PWM3 port.
Refer to follows photo, after the soft…
Part Number: TPS40090 hi all,
the TPS40090 is used as a DCDC interleave boost controller with 2-phase operation application, the input is 35Vdc, the output is 117Vdc&5A, and I use +6V with a 1.2K pull-up resistor on EN port to make TPS40090 work.
In power…
Part Number: TPS40090 Hi Ti experts,
I want to refer to the project files(schematic/PCB document and BOM) of TPS40090EVM-002.
I can not find it at the bottom of the website . So could you send me the project documents.
Thx.
Part Number: TPS40090 Hi team,
Is it possible to use TPS40090 for boost controller? What is the different between buck controller and boost controller? Thanks.
