LT8333 queries

Category: Datasheet/Specs
Product Number: LT8333

Hello,

My name is Vijetha, and I am a hardware engineer. I am designing a boost converter with LT8333 and I have few questions on compensator design

  • I am unable to calculate the DC voltage gain of the modulator because the datasheet does not have the value of modulator transconductance gm (MOD). Due to this I cannot proceed with the frequency response of the power stage.
  • One of the application notes says how to calculate this value, but the datasheet does not contain the value of "the no-load to full-load output voltage swing of the error amplifier"
    • gm(MOD) = (VRSENSE(MAX)/RSENSE)/∆VITH(MAX)

Can you please provide me the value of any one of these above, so that I can calculate the DC gain and thereby the compensator.

Thank you,

Vijetha
