[Review Request] Low Voltage, Flyback converter based, Impulse Generator. Board and schematic

Operating principle: A flyback converter whoose main element is a transformer with four windings of ratio 1:10:10:10, the primary is connected to +24V and to the switching mosfet, while the secondaries are stacked to provide up to 1200V.

The flyback will charge a 1uF capacitor up to the target voltage, which will then be connected to the output via a high side switch controlled by an isolated gate driver.

The flyback will use peak current control, a shunt resistor is present at the source and a comparator will signal to the STM microcontroller when to turn off the primary switch.

The output voltage will be monitored by a voltage divider and an isolated amplifier connected to the STM microcontroller.

If possible, I would like some feedback on the peak current sense mechanism, on the isolated gate drive and on the isolated voltage measurement.

Thank you very much.
