Power Integrations introduced HiperLCS, a family of high-voltage LLC power supply ICs that incorporate the controller, high- and low-side drivers, and both MOSFETs into a single low-cost package. Highly integrated HiperLCS ICs offer the flexibility to optimize designs either for high efficiency, with a maximum efficiency of better than 97%, or for size, by leveraging … [Read more...]
Thermal characterization of power ICs using virtual junction temperature
Thermal experts generally view thermal resistance as a measurable property of a semiconductor device. A system designer, who designs an appliance, is usually not a thermal expert. The system designer just needs a way to determine the size of the external heat sink. At high heat sink temperatures, less power dissipation is allowed in the device. The ratio at which case … [Read more...]
