I applied to install the software PSpice for TI; However, in the software, I could not find the "menu" demonstrated in the tutorial of TI's official website, nor the LM3478 PSpice model, as shown in the following…
Part Number: LM3478 Hi expert,
When the customer uses the LM3478, the FA pin is pulled up to 12V through a resistor, but the LM3478 can still work normally. Is this application feasible? What risks will exist? thanks.
Part Number: LM3478 Tool/software: Hi,
We use the LM3478MMX/NOPB for the buck circuit from 12VDC to 58VDC, and power provide to POE PSE TPS23681PWR, and this circuit is abnormal;
Plesae help to review our schematic diagram and advise if there are…
Part Number: LM3478 Tool/software: Hi, dear.
Sorry for troubling you.
I design LM3478 as a boost controller based on Webench tool.
My initial goal is that it needs to operate in range of Vin = 6 - 23VDC and Vout=24VDC at about 2A currents to charge…

Part Number: LM3478 Dear Sir,
We are using LM3478 IC for Flyback converter and facing below issues.
we could not generate the Gate pulse from LM3478, even though
1. All pins of LM3478 IC are normal.
2. MOSFET is not damged.
3. FA/SD (7th pin…
