Hi,
We are using LM5118 in a design .
Vin - 18 to 60V
Vout - 24V
Max load current 3A
In the sample design generated by WEBENCH there is a resistor connected between RAMP & VCC . What's the purpose of this resistor ? I don't see it mentioned in the datasheet.
thanks
Hi Najma,
his adds additional slope compensation if Vin is > 20V.
