Other Parts Discussed in Thread: LM5035B , LM5100A , LM5035 , LM5045 Hi,
I would like to make full bridge converter using LM5035B, is it possible to make it by simply using 2 separate gate driver like LM5100A for primary side and LM5112A driver for secondary…
Other Parts Discussed in Thread: LM5035C , LM5035B , LM5025C , LM5025B , LM5025A Hi Team, Is seems there is only LM5035C EVM in website for LM5035x series. Should my customer make replacement the IC on EVM if he wants to evaluate LM5035A or LM5035B? Best Regards…
Hi Hamamoto-san,
Since there is no internal fixed dead-time for LM5035C and LM5035B, it is recommended the delay pin resistor not be less than 10k to prevent cross conduction between the primary FETs and SRs.
However, LM5035A does provide 70ns (nominal…
Other Parts Discussed in Thread: LM5035B , LM5025A , LM5025B , LM5025C Hi Team, My customer wants to know the detail difference about soft-stop between LM5035A and LM5035B. I believe LM5035A shows the PWM duty cycle gradually fall to zero with maintaining the…
Alex,
If your customer would like a duty cycle close to 50%, he should use the LM5035B. The maximum duty cycle can be calculated by:
Dmax%=((0.5 X Ts)-T1)/Ts, where Ts is the oscillator time and T1 is the programmable sync rec delay. T1 can be calculated…
