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.

SCALE™-2 2SD300C17
Preliminary Description & Application Manual
Driver Overview
The 2SD300C17 is a driver core equipped with Power Integrations' latest SCALE-2 chipset /1/. The SCALE-2
chipset is a set of application-specific integrated circuits (ASICs) that cover the main range of functions
needed to design intelligent gate drivers. The SCALE-2 driver chipset is a further development of the proven
SCALE technology /2/.
The 2SD300C17 targets medium- and high-power IGBT applications such as windmill and solar converters,
general purpose drives, as well as traction including parallel gate driving of IGBT modules. The 2SD300C17
comprises a complete dual-channel IGBT driver core, fully equipped with an isolated DC/DC converter, short-
circuit protection, active clamping, soft turn-off and supply-voltage monitoring.
