Part Number: LM5157 Other Parts Discussed in Thread: LM5155 Hi ...
I am working on the design in SEPIC based on the LM5157 and I am experiencing some problems. Let me start by saying that the circuit is going to have an input between 7.0 V to 20.0 V and…
Part Number: LM5157 Dear TI team,
I am using IC LM51571RTER as boost converter (Input=10 V, Output=20 V). I have applied 1.2 V across Enable pin of IC (Enable threshold is 0.7 V max) but I am not able to turn on Boost IC.
Note: Bias pin voltage=10 V

Part Number: LM5157-Q1 I want to know which simulation model of LM5157-Q1 support worst case analysis. If the flyback works at the worst condition, will the model reflect the real accuracy of voltage, especially the output?
it looks like this thread is identical to this one:

Hi TI experts,
Please support to review the design in attachment file with following specs:
Output: 23V- 0.2A max => supply for gate driver , that why i chosen not boost but …
Part Number: LM5157 I am building a circuit that uses LM5157 to boost the voltage from Vin: 5V to 12V and Vout: 13.5V (Iout=1A). When the load characteristics were confirmed through actual measurements, the characteristics were as follows.
A voltage drop…
Part Number: LM5157-Q1 Hello TI team,
What is the maximum output current in SEPIC mode with 14V output and 6 to 18V input
I didn't perform any calculations, but I found in WEBENCH that it is limited to 2A?
