Did you attach the load and then enable the IC? 7.5 Ohm is likely too small to start into, but if you add it after you start it should work. See section 8.4.1 in the D/S.
But if you only need 12Vin, the TPS62172 or TPS62150A may be worth looking at…
Other Parts Discussed in Thread: CC2541 , CC3200 , TPS62172 , TPS62730 Hi,
I've been working on a design for a WiFI and Bluetooth Low Energy embedded device for a little while now. I've spent a lot of time figuring out the best components for us to…
Other Parts Discussed in Thread: MSP430F5438A , TPS62172 , TPS62621 I have designed a Power Supply Unit that feeds to MSP430F5438A and PAN1326 module from a 12V supply. For 3.3V - TPS62172 is used For 1.8V - TPS62621 is used The input to TPS62621 is given…
The TPS62162-Q1 is designed to reliably provide 1A output current. It cannot be used for higher output currents. So it is not clear to me what you are trying to calculate here.
Anyway, for a maximum of 400mA load current I would suggest to use TPS62172…
