Why is the MCP1630 the only current mode control chip in the world that allows one to directly set the voltage on the PWM comparator input? (ie so that one can set the peak inductor current).
Chips like the UCC28C43 make this impossible as they have diodes in the way.

I appreciate the HV9910B has an accessible PWM comparator input but the reference is fixed and set too low for us..being just 0.25V…we need it to be 0.5 to 1V….or externally adjustable.
