Part Number: LM3478 Hi,
We encountered an intermittent issue when using LM3478QMMX/NOPB. Details as follows: At 12V supply, the chip operates normally. At 16V power-on, the PWM driver shuts down, then PWM becomes abnormal. Please advise: 1. What could…
Part Number: LM3478 Other Parts Discussed in Thread: LM5155 Tool/software: Hi TI experts! I have encountered an issue with the boost converter based on the LM3478. I've used Webench to design the schematic, so I was pretty sure all should've work well…
Part Number: LM3478 Dears,
When debugging the flyback of LM3478, customer found that the DR output waveform remained at a high level when disconnecting D919 and R949 (disconnecting MOSFET G). Can you analyze if this is normal? LM3478 should be a fixed…
Part Number: LM3478 Other Parts Discussed in Thread: LM5155 Dear TI Support Team,
We would like to inquire whether there are any known usage anomalies or stability risks associated with the 26+ date code batch of LM3478QMMX/NOPB. Has TI received any…
Part Number: LM3478 Tool/software: Hi,
Page 15 of the LM3478 datasheet shows a shutdown circuit, and shuts down if the 10k can pull up to a rail of 1.4V or higher...however, is this still the case if the RFA resistor is as high as 180k?
Part Number: LM3478 Tool/software: Hi Team,
We designed the LM3478 Boost circuit based on the Webench simulation (attached simulation report)

Below are the inputs:
Vin(min): 4.9V
Vin (Max): 5.1V
Current: 0.5A …
Part Number: LM3478 Tool/software: Within the product family of LM3478 I have documentation of PN LM3478MM originally being a standalone part. Has this part been discontinued, and is there a recommended replacement? Is PN LM3478MMX/NOPB similar/equivalent…
Part Number: LM3478 Tool/software: Hello,
I am in the process of re-designing a boost converter with the LM3478 and noticed something in the documentation that didn't match WEBENCH , which left me a bit confused. The datasheet outlines the following…
