Part Number: LM5041B Tool/software: Hello，
Question1：The customer uses LM5041B for DCDC module power supply, with an input voltage of 48V, output voltage of 28V, power of 500W. When the capacitive load value is large, it is about 5000uF. When the module…
Part Number: LM5041A Other Parts Discussed in Thread: LM5041B , Hi Team,
My customer is currently using LM5041A in their design and are facing shortages. They are trying to use our LM5041B, but are facing issues in their testing. Below is their feedback…
HI,
You need to see how much current into Vin, then figure out the biasing power, then using that power to calculate the temperature rise for the LM5041B.
With what you show, if the LM5041B shows over 90C, it looks that device has something wrong already…
Part Number: LM5041B Other Parts Discussed in Thread: LM5034 , LM5022 Hi Sir
we want to design input 200V-400V/DC, output:200~300VDC 1KW output power , Synchronous rectification; we want to use LM5041B(buck+pushpull)，
because the input voltage is 200V-400V…
Part Number: LM5041B Hi team,
My customer is using our LM5041B for “buck+half-bridge”. They connected VIN and VCC together(12V) and the input voltage of Buck is 200 to 400V. The output voltage of buck is 145V and the final output voltage is 28V/18A, as…
Part Number: LM5041 Hi team,
In the LM5041b datasheet, there is a table to show the oscillator's frequency. When Rt=26.7 kOhm, the frequency range is 175~225 kHz. When Rt=7.87 kOhm, the frequency range is 515~685kHz. The customer wants to know the frequency…
Part Number: LM5041B Other Parts Discussed in Thread: LM5041 Hi sir
pls help check LM5041B whether can be used design as above application，if can，pls help provide same application reference design ，tks！
1: The input is 36~75VDC, the output power is 400W, 600W, 800W. 2: The input…
Part Number: UC2827-1 Other Parts Discussed in Thread: LM5041 , LM5041B , LM5041A Hi team,
Please provide SPICE model for UC2827 to simulate in LTSpice or Simetrix.
Hi Tim
There seems to be a consensus that a current fed converter is better for very high voltage applications. You get some protection against shoot through currents on the primary and you don’t need an inductor in the output
