    LM5022: Design now working at high load

    Part Number: LM5022 I'm designing a boost regulator to go from 12 V to 60 V up to 100 W. It is working very well at smaller loads, but something happens at larger loads. The regulator worked fine at 35 W, but at 50 W, when I turned the power on...

    RE: Wide Input - Output Is not coming out

    Thanks for the quick reply, As per your suggestion, I checked the voltage at VCC, CS pin, and Output Pin of LM5022, and these are as follows. VDC Supply = 200 Vin= 14.12 V VCC= 4.1Volt Output pin = 1.8 V (Removed R20 ) CS pin = 1.8 V (Removed...

    LM5022: Efficiency way off, much lower than expected based on webench design.

    Part Number: LM5022 Using webench to model a 12-36V IN, 52V, 1.25A boost converter. Charts show efficiency at 94% and up, but I'm getting way less somewhere around 84%. This of course, leads to thermal shutdown with any considerable load. FET and...

    LM5022SEPBLDT_NOPB: Humming noise when input equal to desired output at max load

    Part Number: LM5022SEPBLDT_NOPB Hello, We have designed a boost regulator using LM5022 for 150W load : Vin = 20 to 48V; Vout = 48V Vin = 48 to 60V, Vout = Vin. This works for all the input range except when Vin = 48V. There's a loud humming...

    LM5022: Unstable Operation

    Part Number: LM5022 Hi, team. We designed a booster circuit from 36V to 300V with the LM5022. However, as shown in the attachment, the Gate waveform works with Dmax, Dmax, Ton (min). 300V is obtained, but is this phenomenon due to instability or Dmax...
