Hi Sanon,
The Launchpad is powered by the USB by default. It has a footprint for power connector for an external 5V DC input.
Please find a proper power regulator from ti.com:

Part Number: LM5116 Other Parts Discussed in Thread: LM5576 , LM5005 , LM5146 , LM5145 Hello all,
We utilized WEBENCH to design the following power converter circuit for our design:
However, after attempting to model this circuit in PSpice for TI…
Hi Bob,
I agree with your statement that fault will be active when current is limited. That is the expected operation but in this case it does not seem to be doing this. In answer to your questions...
1. 266mA is the nominal Ios calculated current…
Hi Kanemaru,
You can use the LM5005 WEBENCH model for further guidance. There is an internal 25uA current source contributing to slope compensation (see equation 2 in the LM25005 datasheet), and using a very large inductance could shift the emulated…
Hello Geo,
Apologies for the delayed response.
The average value of the inductor current in the inverting buck boost topology is not same as the output load current (as in the normal Buck topology).
The average value of the inductor current is given…
Other Parts Discussed in Thread: LM5005 Hi,
I have a design with LM5005. Here are the main parameters:
Vin=48V
Vout=12V
Switching Freq=387kHz
Scope picture at swithing node:
My problem is that there is a huge high frequency noise at the…
