SCALE™-2+ 2SC0108T
Preliminary Description & Application Manual
Dual Channel Ultra-compact Low-cost Driver Core
Abstract
The new low-cost SCALE™-2+ dual-driver core 2SC0108T combines unrivalled compactness with broad
applicability. The driver was designed for universal applications requiring high reliability. The 2SC0108T drives
all usual IGBT modules up to 600A/1200V or 450A/1700V. The embedded paralleling capability allows easy
inverter design covering higher power ratings. Multi-level topologies are also supported.
The 2SC0108T 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+ 2SC0108T
Preliminary Description & Application Manual
Driver Overview
The 2SC0108T 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 SCALE-2+ chipset further integrates the Soft Shut Down (SSD) feature described in
the paragraph “Soft Shut Down (SSD)” on page 16.
The 2SC0108T targets low- and medium-power, dual-channel IGBT applications such as general purpose
drives, UPS, solar converters and medical applications. The 2SC0108T comprises a complete dual-channel
IGBT driver core, fully equipped with an isolated DC/DC converter, short-circuit protection and supply-voltage
monitoring.
