Maximizing power density and thermal performance in power-module designs
https://www.electronics-lab.com/maximizing-power-density-thermal-performance-power-module-designs/
Power-module designs require high power density, excep-tional thermal performance and a full feature set in order to be competitive. One way that power-module designs can meet these needs is with buck controllers with exter-nal metal-oxide-semiconductor field-effect transistors (MOSFETs) in their power architecture. Buck controllers with external MOSFETs allow current scalability and provide superior thermal spacing—both […]

Bootstrap Circuit in the Buck Converter explained
https://www.electronics-lab.com/bootstrap-circuit-buck-converter-explained/
This application note explains the step-up circuit using a bootstrap capacitor. In buck converters, this circuit is used when the high-side switch is the N-ch MOSFET. The configuration of the circuit in proximity to a buck converter depends on the polarity of the high-side switch.When a P-ch MOSFET is used for the high-side switch, there […]
