Part Number: LM5170-Q1 Other Parts Discussed in Thread: LM5170
Tool/software:
Hi,
I was doing the simulation in Tina using LM5170 Model for 2 phase Boost converter, output voltage is 14V and Input voltage is 8V, Full load current i am doing for 3 different…
Hi Feng,
Thank you for your response.
As per the datasheet the maximum Duty for LM5170-Q1 is,
Dmax= 1-(200nS+56nS) *100K=0.97 With 10K DT resistor and 56nS Dead time.
I am operating at 15.5V input and 14V output, ie Duty=14/ (15.5*0.95) =0.95
So,…
Part Number: LM5170-Q1 Tool/software: We are often experiencing the LM5170-Q1 IC damaged with VCC to AGND was measured only less than 200ohms! We do have a LDO to prevent over voltage glitch to VCC but the problem remained. Please let me know if you have…
