Hello, if you use TPS62740, you can only start with a lower setting for Vout and after increase to the target value (3.3V). This will decrease a bit the inrush current. You can also have a look at this device TPS62821 because has a slower soft start.…

Hi, guys. It's my first time using the INA260. I'm trying to create a custom PCB that uses micro USB 5V.
This will be connected to the buck converter…
Hello,
I can suggest TPS62821 for mobile computing and network cards with Iout= 1A and QFN package. If you want you can look for also other suitable devices for your application at this page: www.ti.com/.../overview.html
Hi Daniel! I hope you're doing well.
The TPS62806 supports Vouts down to 0.4V. If you need lower, you need to feed a voltage into the FB pin on a device like TPS62821/5. I will email you some preliminary documents on this topic. Here are 2 older ones…
Hi Chris, I read the above document that you shared. It is good to know about the design analysis and the right selection of parts for maximizing the battery life. I have few doubts about TPS62821.
Is there a Webench tool available for TPS62821? Can…
This is difficult spec to meet.
It looks like this device can not do what you need.
Be sure that your input supply is not drooping at the VIN node of the device
due to drops in the wiring.
You might try the LMR43603.
Or TPS62821 if you only need…
Hi Steve,
I would like to suggest some of our newer smaller highly efficient buck converters (Assuming requirements as Vin-5V Vout-3.3V, Iout -1A): TPS62840, TPS6282x or TPS6280x. Please have a look at the datasheet and let me know if you need further…
Hi Muhammed, To make this backup circuitry you would need to use two extra diodes so the 3.7V battery could take over and power your circuit while the main power supply is down. I recommend the TPS62821 for the 1.5V rail at 200 mA max. And the TPS62827…
Hello again PJs,
The TPS62821 that we discussed before has a longer SS time. Otherwise, there is this application circuit, found on the product page: www.ti.com/.../slva307b.pdf
Part Number: TPS55340 Other Parts Discussed in Thread: TPS62821 , TPS568215 Dear TI :
I use tps55340 as boost circuit: 12 V ----> 24V 0.5A . efficiency>90% use tps568215 as buck circuit: 12 V ---->5.2v 3A. another Buck circuit tps62821: 5.2V ---> 3…
