LMR23630: Slope Compensation Ramp on the functional block

GARAM AN

Part Number: LMR23630

Hello,

How the output of error amplifier is changed after meeting slope compensation ramp?

what is the spec of the slope compensation ramp?

Thank you

    Hi

    error  amplifier  will almost keep its voltage when you have a fixed Vo, Io, Vin. Erro error amplifier voltage reduce the ramp voltage compare to the current sense voltage. 

    we don't have the spec for slope compensation, but you can follow LMR23630 spec to design the inductor. Too small inductance will cause subharmonic oscillations.

    Thanks
