HotRod Quad flatpack No Leads (QFN) are leadless packages specifically designed for power applications. The small footprint, standard QFN pitch, low parasitics along with high current capability of these packages are ideal for power converters application. The electrical connections are made via lands on the bottom side of the component to the surface of the connecting substrate (PCB).

Power dissipation performance must be well understood prior to integrating devices on a printed-circuit board (PCB) to ensure that any given device is operated within its defined temperature limits. When a device is running, it consumes electrical energy that is transformed into heat. Most of the heat is typically generated by switching devices like MOSFETs, ICs, etc. This application report discu - Semiconductor and IC Package Thermal Metrics (Rev.
