Other Parts Discussed in Thread: TPS40305,
I need to step down a 2S IMR battery to 5V, with a max load of ~2.5A. Battery life and PCB area requirements are both challenging. Webench suggested the TPS40305 and I’d like to evaluate it using the TPS40305EVM-488. However,
1. The EVM’s data sheet says repeatedly that the input voltage range is 8V – 14V. Why, when the input voltage range for the TPS40305 is 3V – 20V? What am I missing?
2. Changing the feedback resistors to give 5V output is trivial, but do you have a utility for calculating compensation values?
3. Any other suggestions?
