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:
LM5022
SEPBLDT_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...
