SCALE-2 2SD300C17 SCALE-2 2SD300C17 Description & Application Manual Dual Channel High-quality and Low-cost SCALE-2 Driver Core Abstract The SCALE-2 dual-driver core 2SD300C17 is a second source to Infineon s 2ED300C17-S and 2ED300C17-ST. The driver is fully pin and function-compatible to the 2ED300C17-S/2ED300C17-ST and was designed for applications in which high reliability is expected. The use of Power Integrations highly integrated SCALE-2 chipset allows 63% of the components to be dispensed with compared to the 2ED300C17-S/2ED300C17-ST. This advantage is impressively reflected in increased reliability (function and MTBF) with simultaneously lower costs.
