Part Number: LM51231-Q1 Tool/software: Hi team，
The LM51231 datasheet defines the minimum SW-AGND voltage as -1v (50ns). Harman measured the negative voltage of SW to GND as -3.9v. Is there a risk? Please help confirm.
Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM5122 Tool/software: Hello,
I have used the Excel designcalc for the LM5123 but the minimum output capacitance displayed is 3454,50 uF which sounds like a lot. I have done the same calculations…
Part Number: LM51231-Q1
Tool/software:
I am implementing a 28V boost circuit, designed to take in 24V input. I tested on the 5123 EVM, and then in an effort to minimize risk tried to keep my design 1:1 with that, just changing the VREF set point resistors…
Part Number: LM51231-Q1 Tool/software: Hi
ls check if we have following spec.
Thanks. The requirements for the step up converter (boost) function are as follows.
Is there any chance to help find a suitable original?
Power: 160W or above
Output Voltage…
Part Number: LM51231-Q1 Tool/software: Hello,
I am trying to calculate losses for the synchronous MOSFET. In table 2-2, the body diode conduction loss uses a term of (Vload*Fsw)/2. This results in a very high calculated loss. I think the voltage should…
Part Number: LM51231-Q1 Tool/software: Dear Team, I am designing a 12 to 24V 240W boost converter using the QRGRRQ1 IC. I obtained the attached design from the webench designer tool. However, upon reviewing the EVM, I noticed that they are using a total…
Part Number: LM51231-Q1
Tool/software:
Update : At above about 40W, the output voltage drops. It is not due to insufficient input power available, as I have tried various sources. I have noticed that the duty cycle changes, which suggests that the LM51231…
Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM5123-Q1
Tool/software:
We are currently testing a boost converter design with the LM5123-Q1 boost controller and are having questions regarding the bypass mode of the controller.
We’re having…
Part Number: LM51231-Q1 Other Parts Discussed in Thread: LM51551-Q1 , LM51551 , LM5155 Tool/software: Dear Sirs,
we are not sure if we can use LM51231-Q1 to design a rather unusual boost converter:
Vmin = 2.5V Vnom = 3.3V Vmax = 3.7V Vout = 20V Iout = 3A
It…
Part Number: LM51231-Q1 Other Parts Discussed in Thread: TAS5825P Tool/software: Hi
We are using the LM51231Q1 in our audio product for dynamic output voltage management in conjunction with the TAS5825P's Hybrid-mode.
The maximum output power reaches…
