ncp51820

I'm building a TDR pulse generator using a single GaN FET (TP65H300G4LSGB) in high-side configuration, driven by NCP51820. The drain is at 40 V, and the source goes through a 50 Ω resistor to GND. Output is taken from the FET source. My Final target is upto 200v. Pulse specs: ~40 V amplitude...
