Part Number: LM3478 Other Parts Discussed in Thread: LM5156
Greetings, I hope somebody could help me. I'm trying to design a SEPIC converter based on LM3478, with input voltage range 12-36V, and output 24V 2A. I'm calculated all relevant values of components…
Part Number: LM3478 I have successful past designs with the LM3478 and would like to stay with the part. I recently have an application where it would be useful to convert about 45 watts of power (12Vin nominal to 24Vout nominal) and Webench does not…

Part Number: LM3478Q-Q1 Other Parts Discussed in Thread: LM3478 Hello, good day. Our customer have a problem :
Does the lm3478 chip control the voltage loop and current loop together? For example, in this picture, during normal operation, if the input…
Part Number: LM3478 While playing around with design parameters for a LM3478 design, I noticed that Webench's SEPIC schematic and Boost schematic differ in the placement of Cfilt for monitoring Vsense at the Isense pin.
Boost:
SEPIC:
Note that…

Hi Saiprakash ,
Thanks for the update. If your inductor is heating up a lot, this may be related to a very large current ripple, resulting in larger inductor losses. You can calculate your current ripple using our power stage designer tool. Please choose…
Part Number: LM3478 Hi,
In a booster circuit using lm3478 , The output oscillates when the load changes.
Vin is +24V ,Vout is +80V and 0.3A .
The circuit diagram and oscilloscope image are shown.
Please give me advice to solve this problem.
