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…
Hi Emanuel,
Thanks for the update. So you see a difference just by changing the feedback resistor sum? This would mean the issue is not only related to the current sensing circuit.
It is definitely possible that the stability of system can suffer by the…
Part Number: LM3478 Tool/software: Hello
I am designing a solar harvesting power supply with a Talentcell 6V 6Ah LiFePO4 Battery Pack. The battery has protection for over-charge, over discharge, over current and over temperature. If the battery is treated…
Hi Niklas：
We disconnected LM3478 and TPS23861, and separately tested the LM3478 booster circuit and TPS23861 POE circuit. The test results are as follows 1. LM3478 test NG; 2. TPS23861 POE circuit test OK: The input power of TPS23861 adopts the regulated…
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 any…
Part Number: LM3478 Tool/software:
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 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 some…
Part Number: LM3478 Other Parts Discussed in Thread: LM5155 Tool/software: Hi,
Q1. I believe that the variation in V_SENSE and V_SL ratio described in the Electrical Characteristics of the data sheet is temperature dependent, is this correct? Also, are…
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…
