Part Number: TPS82740B Hello,
We have a customer asking for the lead finish for this device. In the datasheet and the website, it simply says "Call TI".
Could someone please look in to this?
Thanks,

Part Number: TUSB8020B Other Parts Discussed in Thread: TPS82740B Hello,
Will a 200mA buck have enough headroom for the 3.3V supply? I am planning on using the TPS82740B module.
The datasheet mentions a nominal input supply current of 93mA for 3.3V rail…
For a wearable, either TPS62743 or TPS82740B are very small solutions.
It's not clear what you mean by 5V at 15 mA. If this is your input source's capability, it is greater than your required output power. This is not possible.
Understood. Sometimes customers need the boost functionality to keep Vout above a higher minimum and to overcome IR drops (in the battery impedance, PCB trace, etc.) in their system.
The TPS82740B is an equally small buck module with much lower Iq.…

I am looking for a 3D model of the TPS82674 (uSIP-N8 package). Do you have any STEP model available?
Best Regards,

I've not seen a single chip with a negative voltage but 2 discretes can do.
The TPS60400 family can easily make your -5V.
For the 3.3, the TPS82740B is the absolute smallest device. TPS62237 would be a discrete version but still small.
Yes, you have a different battery than the reference design, which has a different voltage range, which requires a different power solution. What voltage range can your loads accept?
If you must use 3.3V, then the TPS63051 is the best option, as you…
