Dual Channel Ultra-compact Low-cost SCALE™-2 Driver Core
Abstract
The new low-cost SCALE™-2 dual-driver core 2SC0108T2Dx-xx combines unrivalled compactness with broad
applicability. The driver was designed for universal applications requiring high reliability. The 2SC0108T2Dx-xx
drives all usual IGBT modules up to 650V (2SC0108T2Dx-07) or 1200V (2SC0108T2Dx-12). The embedded
paralleling capability allows easy inverter design covering higher power ratings. Multi-level topologies are also
supported.
The 2SC0108T2Dx-xx is the most compact driver core available for industrial applications, with a footprint of
only 45mm x 34.3mm and an insertion height of max. 16mm. It allows even the most restricted insertion
spaces to be efficiently used.

SCALE™-2 2SC0108T2Dx-xx
Preliminary Description & Application Manual
Driver Overview
The 2SC0108T2Dx-xx is a low cost 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 2SC0108T2Dx-xx targets low- and medium-power, dual-channel IGBT applications such as general
purpose drives, UPS, solar converters and automotive applications. The 2SC0108T2Dx-xx comprises a
complete dual-channel IGBT driver core, fully equipped with an isolated DC/DC converter, short-circuit
protection, advanced active clamping and supply-voltage monitoring.
