Part Number: LM3478 Other Parts Discussed in Thread: UCC3803 , LM5155 Dear Support Team,
I'm currently designing a circuit that requires a power supply with the following requirements: - Input from a single 12V battery - Two outputs around +24V and…
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…
Part Number: LM3478 Hello TI experts,
I was trying to design a SEPIC converter using a LM3478. My requirements are Vin -> 3-24V and Vout -> 5V with 3.6A.
I was able to do Vin -> 3V to 5V with the Vout i wanted. But when i pass the value of 5V in the…
Part Number: LM3478 Other Parts Discussed in Thread: LM5155 , LM51551 Hi There,
I am using LM3478MAX in a Sepic topology for a buck-boot operation. I have followed the Webench design guide. The issue is when I try to power ON the circuit it loads down…
Part Number: LM3478 Other Parts Discussed in Thread: CSD18543Q3A Hi,
Good day,
I am using LM3478 in buck boost config where my input range will be 10-15V and my output will be 12V and 3.5Amps max. In my current implementation the mosfet is heating…
Part Number: LM3478 hi teams:
The customer has a product that uses TI's LM3478, with an input of 4-17V and an output of 5V/0.3A.
Currently, there is a problem that when the input power fluctuates at low frequencies, the inductor L2 will make a noise…
Part Number: LM3478 In the datasheet of the LM3478 I have read that the gate of the mosfet must be connected to the DR pin. But my question is if an external driver could be added, which would receive the PWM signal from the DR pin, in order to have a…
Part Number: LM3478 Other Parts Discussed in Thread: LM5022 , , POWERSTAGE-DESIGNER I asked Webbench for a SEPIC converter using the LM5022 or LM3478 20V-60V input 48V @ 1A output, and it says it can't, but it doesn't say WHY it can't.
I would like…
Part Number: LM3478 Hello,
I want to use LM3478 as a simple led driver, schematic is attached. The problem is that I can't get a stable duty cycle on the DR output. Components mostly follow the WEBENCH POWER DESIGNER. What went wrong?
Part Number: LM3478 I have designed a boost DC-DC convertor circuit using LM3478. The input voltage is 12V,13A (via AC-DC Power Supply) and the output voltage 24V,5A. Circuit has been worked fine for few days and suddenly the convertor is not working…
