Part Number: TPS22990 Other Parts Discussed in Thread: TPS22997 Hi TI Support,
I have an application in which I switch a 1V8 rail with the TPS22990. I have connected a 3V3 power supply to the Vbias pin, but the 1V8 (VIN) will be present (just) before…
Part Number: TPS22990 Hello,
I would like to control the Ron pin of the TPS22990 as shown in the circuit. I want to apply 5V to Ron during power ON, and for operations like H/W Reset, I intend to control it from the MCU to apply 0V. However, I am facing…
Part Number: TPS22990 Hi Team,
My customer would like to add 0.047uF on CT pin to control the start-up time around 2ms. Regarding to Table 1 in the datasheet, The Ct value is up to 0.01 uF.
Does it allow them to add Ct value more than 0.01uF? and work…
Part Number: TPS22990 Hi team,
Could you please teach me the parasitic capacitance & inductance of this device? A customer needs the parameter to run simulation.
Best, Zeming
Part Number: TPS22990 Hi team,
My customer is using TPS22990 for their new design, and t hey also plan to test the SOA curve by multiplying the Irush and Vds, and they want to know the maximum value of product of Irush and Vds.
Furthermore, they also want…
Part Number: TPS22990 Hi Team,
Can you please help us with our customer's inquiry below?
In my applications are the capacitive load 1-2mF at 3.3V, according to datasheet it is possibly to use up to 10nF CT capacitor and at 3.3V is the output voltage…
Part Number: TPS22990 Other Parts Discussed in Thread: TPS22950 , TPS22997 Hi team,
Good day!
My customer is using TPS22990 for their design now, and they want to know more details about the OC protection of TPS22990, they want to know in which current…

Hi Team,
The calculation of Rise Time is shown on page 17 of datasheet . But there is a slight difference between table1 and my calculation as below:
tR=(0.011 * VIN + 0.002) * CT + 4.7 * VIN + 7.8 In case of VIN=5V, CT=10000pF My…
Part Number: TPS22990 Hi there,
Do you have maximum allowable start-up current for TPS22990N?
I'm asking this because I saw huge inrush current forced TPS22990N to turn off, so I want to calculate the feasible soft-start time.
I know the total capacitance…
Part Number: TPS22990 Hello,
I have an application where we are using some TPS22990 load switches for different power rails but none higher than 3.3 VIN with a 5V bias. On the datasheet, besides the max rating, it says the following about the CT pin: …
