Half-Bridge Driver with Inbuilt Oscillator

This is a Half Bridge with Inbuilt Oscillator project that uses the NCP1392B, a self-oscillating high-voltage MOSFET driver, and two IRF540 MOSFETs. This project is specifically designed for applications that employ half-bridge topology.

The operating frequency of the driver can be adjusted from 25 kHz to 100 kHz using a trimmer potentiometer (PR1). Additionally, the project features adjustable brown-out protection, ensuring that the bulk voltage operates within the correct range. An internal 100 ms or 12.6 ms PFC delay timer guarantees that the main downstream converter will be turned on only when the bulk voltage is fully stabilized. The device also provides a fixed dead time, which helps reduce shoot-through current.
