Project development, ideas, and suggestions / Synchronous MOSFET Driver for Inverting Buck-Boost topology
I'm on project to make Inverting Buck-Boost converter that digitally controlled using microcontroller by using feedback on ADC and send duty cycle with specific frequency on PWM pin.

I'm using ADP3110A for driving the mosfet, in the datasheet is available the schematic of Buck topology (Figure 4). I'm using microcontroller to enable/disable converter via OD pin (pin 3) and send PWM via IN pin (pin 2). As I know it will need level shifting to match reference ground.

Anyone can help me, what the best schematic for level shifting on OD and IN pin so I can use microcontroller to enable/disable and driving PWM to ADP3110A?

Here's my schematic:
