Other Parts Discussed in Thread: LM25117, LM25117-5117QUICK-CALC,
Hi TI Engineer,
My question is what is minimum input voltage can allow LM25117 to output 5V or 3.3V?
I have tried to use "LM25117-5117QUICK-CALC — LM(2)5117 Quick Start Calculator", but it doesn't work.
Target output voltage, VOUT [V] = 5
Desired minimum start-up voltage, VIN(STARTUP) [V] = 4.5
It won't have any error message. Is it correct?
Actually, I am looking for formula/method can calculate Vin minimum voltage when LM25117 output voltage is 5V or 3.3V.
Thanks in advance,
Nick Huang
