A chip for smooth dead time adjustment

[AlexRG]

Hello friends! I'm looking for a chip that could smoothly adjust the dead time. I drew an approximate diagram.



What is required:
- power supply +5V
- 3.5MHz PWM input (if more, only better)
- two outputs, direct and inverted
- load 15-20pf
- there must be a pin for connecting a resistor. This resistor needs to adjust the dead time from 10 to 100 ns. If wider, only better. But, not lower than 10-15 ns.

And most importantly, it is very desirable to have a body that has legs. That is, SO, SOP, SOIC, SOT23, etc. BGA mounting and blow dryer I can not pull..

For example and understanding. The dead time adjustment mechanism using just one resistor is implemented in many drivers, for example NCP51561, UCC21530. Shouldn't there be a simple microcircuit for weak signals?) Please help me find one.
